I really dislike the tone of the explanation. I mean it's so negative about the features! Not that they are all useful, but isn't this a wiki and should be neutral? It takes also the fun out of it. I would like a screaming while falling phone and the relativity thing would be great for teaching relativity! [[User:RecentlyChanged|RecentlyChanged]] ([[User talk:RecentlyChanged|talk]])

Travelling at above the simulated speed of light should give an imaginary time dilation, not a negative time dilation.
gamma = 1/sqrt{1-v^2/c^2}
Thus, after such travel, the value of the clock would be a complex number. [[Special:Contributions/108.162.219.35|108.162.219.35]] 15:42, 2 May 2014 (UTC)

'''Changed the speed of light to 2.99x10^8'''
:You guys should probably clarify that the relativisic affects actually depend on how long your trip is or how long you wait to sync your phone. For relativity to be observable on a 12 hour trip, Minimum speed for a phone would have to be 300 m/s or 3000 m/s for the clock to measure even a microsecond/millisecond difference in time. This is well known thanks to the certain [https://en.wikipedia.org/wiki/Time_dilation#Velocity_and_gravitational_time_dilation_combined-effect_tests time dilation experiments with planes]. Your GPS chip helps account for an error of [https://en.wikipedia.org/wiki/Error_analysis_for_the_Global_Positioning_System#Relativity 7 to 47 microseconds per day]. My point is in terms of time dilation, relativity mattering depends on how long a trip or waiting for synchronization is. By synching, I literally mean with the atomic time clock or with a GPS satellite. The synchronization of your phone with satellites is actually a couple of hundred microseconds, so normally even a light changing clock might not have as noticable changes as you might think.

; relativistic effect
Forgive me if I'm wrong, I'm not a physicist but the above explanation says that relativistic time dilation affects only occur at a significant fraction of the speed of light. It is my understanding that time dilation occurs at any speed, but is only perceptible/noticeable/measurable at very large fraction of the speed of light. Unless I'm mistaken the above it should reflect this. [[Special:Contributions/173.245.56.91|173.245.56.91]] 22:24, 2 May 2014 (UTC)

; putting "Relative" back into relativity
First time poster, please forgive my transgressions :)
My understanding regarding relativistic effects is that, for a given frame of reference (e.g. phone operator travelling at 0.9c) would be absolutely none. Relativistic effects (as I understand them) would only apply between two different frames of reference. The only effect I can see in this case is if you are moving towards, or away from the phone while operating, and red/blue shift of the radio frequencies. In general, wifi and bluetooth are used locally so wouldn't apply; only the phone network would be affected.

Also, perhaps the adjustable speed of light is a reference to the the game "A slower speed of light" by MIT Game Lab http://gamelab.mit.edu/games/a-slower-speed-of-light/ (in which you walk around collecting objects; each object slows light down, and increases relativistic effects).

: There are other indications that the phone is at least partly biological, this being the strongest evidence of that. Insects could be the power source for the biological part(s). [[Special:Contributions/173.245.54.45|173.245.54.45]] 14:07, 2 May 2014 (UTC)

'''Siri'''

Could the Siri bit be a reference to Portal? When I first read it, I remembered this GLaDOS quote: "Your Aperture Science Weighted Companion Cube will never threaten to stab you, and in fact cannot speak. If your Weighted Companion Cube does speak, please disregard its advice." Could be completely wrong; just a thought. [[Special:Contributions/173.245.54.51|173.245.54.51]] 10:09, 2 May 2014 (UTC)

'''Realistic case'''

Car telephones and the first cellphones were rather expensive, at least in Germany fake "realistic cases" were sold without any working electronics in it. Usage was to impress silly friends. {{unsigned ip|173.245.52.204}}

I thought this was aimed at the iPhone. Apparently these have an elegant case, but I have never actually seen one. Everyone I know covers their iPhone with some hideous plastic monstrosity, since the design is not practical.--[[Special:Contributions/108.162.218.59|108.162.218.59]] 14:10, 2 May 2014 (UTC)

Could possibly be a reference to the "Realistic" brand, which was used on various products sold by Radio Shack (U.S. electronics retail chain) from 1954 to some time in the '90s.[[Special:Contributions/108.162.219.76|108.162.219.76]] 16:14, 2 May 2014 (UTC)

I am not a native speaker of English. I thought the joke was on the double meaning of "case", meaning both "something that happened or might happen" (like "realistic scenario") and "something that covers something else". Does that make sense to you guys? [[Special:Contributions/108.162.219.17|108.162.219.17]] 10:06, 6 May 2014 (UTC)

'''Price includes 2-year Knicks contract.''' ... but a contract with the Knicks would only appeal to pro basketball players.

Nonsense. Lots of "regular" folks would buy this phone it it meant they got to play in the NBA. [[Special:Contributions/199.27.128.84|199.27.128.84]] 16:26, 2 May 2014 (UTC)

This may also be an indirect way of stating that it is incredibly expensive, seeing as those sort of contracts usually involve ''you'' getting compensated. --[[Special:Contributions/108.162.216.33|108.162.216.33]] 13:41, 3 May 2014 (UTC)

"Your mobile world just went digital" is an inversion of the marketing-speak that was common when what we'd now regard as smartphones first began to be adopted by the mainstream (iPhone/G1 era, since Symbians, Blackberries, and early WinMo tended to be business or enthusiast devices). People already ubiquitously e-mailed, browsed the Web, etc...what was presented as 'new' was that you could now do it from your phone. [[Special:Contributions/173.245.54.58|173.245.54.58]] 19:09, 2 May 2014 (UTC)

I think the "Under certain circumstances, wireless transmitter may control God" statement might be a reference to how transmitting devices have to comply with FCC regulation and not interfere with aircraft or government communications. Perhaps this phone is intended to be noncompliant so as to control high-level electronics, even at supernatural levels.

'''Frictionless'''

You could hold a frictionless phone just by hooking your little finger under the bottom edge, regardless of friction gravity will hold it into your hand. Just like you could leave it in a bowl without it jumping out. [[Special:Contributions/108.162.229.72|108.162.229.72]] 19:12, 2 May 2014 (UTC)

Unless you held your pinky perfectly balanced, horizontal and motionless, a frictionless object would slide right off it, as it would off any flat surface that is not perfectly horizontal.

Wouldn't you be able to hold it somewhat like a normal phone, if you hold a finger under the bottom of it? [[Special:Contributions/173.245.54.54|173.245.54.54]] 17:08, 3 May 2014 (UTC)

Saying a frictionless phone can't be held is like saying prisoners would slide out of prisons if they had frictionless surfaces. [[Special:Contributions/108.162.237.218|108.162.237.218]] 14:50, 4 May 2014 (UTC)

'''Root needed'''

I think that needing root for ajust the volume may be a allusion people needing to root Android to change fonts or to take screenshots (untill version 4.x). [[User:FlavianusEP|FlavianusEP]] ([[User talk:FlavianusEP|talk]]) 23:04, 2 May 2014 (UTC)

'''Alternative meaning: The spirit of xkcd'''

I think there's a secondary possible interpretation for this comic -- that the various features of the phone represent the overall "spirit" or "attitude" of xkcd, in a way reminiscent of an early strip -- http://xkcd.com/207/ -- about "what xkcd means." More specifically, a common theme in xkcd is taking advanced concepts in science and technology, and applying them to whimsical, humorous, impractical, or outright impossible uses. Several of phone's features -- such as the simulated speed of light -- touch on the same theme. Wordplay, another common xkcd theme, is present as well; and the anthropomorphism of technology, along with making devices appear 'cute', is also present, and also is something that has come up in xkcd many times in the past.

The comic is called "xkcd Phone", after all -- I think simultaneously with being a parody of phone advertisements, the comic is also meant to show us what a phone that fits into the xkcd world would be like. [[Special:Contributions/108.162.241.114|108.162.241.114]] 17:52, 3 May 2014 (UTC)

'''Blowing out candles....'''

For the birthday candles thing: I do remember seeing a video ad for an app back when the iphone was first opened up to outside developers that would turn the phone into a fan, and it demonstrated that it was strong enough to blow out a birthday candle. Seemed quite useless at the time. Still does today for that matter {{unsigned ip|108.162.215.47}}

'''Side-facing camera'''

I thought the joke here was that the camera ''only'' contained a side-facing camera rather than a side camera in addition to a front and back camera. While you can see the camera on the side, you don't see a camera on the front and they don't talk about a rear camera. It'd be pretty annoying to use a side-facing camera for anything but the surreptitious case you described. [[User:S|S]] ([[User talk:S|talk]]) 16:58, 4 May 2014 (UTC)

'''Do not submerge in water'''

I assumed this was also referencing the 4chan, etc pranks with the waterproof iPhone [[Special:Contributions/173.245.55.79|173.245.55.79]] 18:41, 5 May 2014 (UTC)

'''Wireless'''

A completely wireless phone would not be unuseable. The only wire phones need nowadays is for recharging their battery, but this can be done by induction, like with the Qi system with which some Nokia and Google (Nexus) phones are compatible.

173.245.53.114: /* Explanation */ Described the tradition of the colored balls, and described the spectrum from fire

{{comic
| number = 1308
| date = December 25, 2013
| title = Christmas Lights
| image = christmas_lights.png
| titletext = Merry Christmas from xkcd!
}}

==Explanation==
{{incomplete|Check grammar, check spectra and reference good fits to what is here}}
Each light in this Christmas scene is represented by its {{w|electromagnetic spectrum}}, which shows in a graphical form how much energy is radiated by each wavelength of light.

These graphs cover only the visible radiation plus some infrared and some ultraviolet. There are 4 distinct spectra in this comic:

In the center of the image, between Beret Guy and the couple Cueball and Megan appears a light spectrum of a fire, notable because it emits a lot of energy in the infrared band (The left zone of the spectrum), emitted typically from hot sources, and in the red and orange zone (typical colors of a fire)

In the right of the comic appear some spectra arranged in the form of a Christmas tree. There are 3 different spectra in this "Christmas tree":

At the top appears a complex spectrum, possibly that of a white LED (see [http://led-brdf.wikispaces.com/Introduction+to+LEDs here]), representing the tradition in some cultures of putting a star at the top of the Christmas tree.

In the branches there are two simpler spectra, one with a peak in the green zone, representing a green LED, and other with a peak in the red zone, representing a red LED, both of them represent the tradition of putting colorful decoration in the tree, especially colored balls.

==Explanation==
{{incomplete|Check grammar and add details about the star spectrum}}
Understanding this comic requires knowing about electromagnetic spectrums.
In a nutshell, an electromagnetic spectrum is the scientific way of representing the amounts and type of radiation than a specific source emits. In this comic apears a subtype of these, a light spectrum, that shows the visible radiation, some infrarred and some ultraviolet. More detailed info on wikipedia({{w|Electromagnetic spectrum}}).

There are 4 graphs in this comic:

In the center of the image, between the couple Cueball and Megan and Beret Guy appears a light spectrum of a fire, notably because it emits a lot of energy in the infrared band (The left zone of the spectrum), and in the red and orange zone (typical colors of a fire)

In the right of the comic appears some spectrums shaped in the form of a Christmas tree. There are 3 different spectrums in this "Christmas tree":

In the top appears a complex spectrum, possibly even from a real star, representing the tradition of putting a star in the top of the Christmas tree, representing the Star that guided the Three Wise Men in Christianity.

In the "leaves" there are are two simpler spectrums, one with a peak in the green zone, representing a green bulb, and other with a peak in the red zone, representing a red bulb
