how can I know if it's an iphone 4 or 4s by only looking at the default desktop.
I have been asked by a person with email but without internet access, who is going to be given a cell phone by a visiting relative, how one can know if it's an iphone 4 or 4s by only looking at the default desktop. In other words, the questioner can have a jpg sent ahead of time. Thanks for any help, and a link to the default desktop of a 4s would be sufficient. (I myself am old enough not to want or have a cell phone, and am clueless.) Thanks. μηδείς (talk) 03:53, 7 June 2015 (UTC)
 * From what I read just now here and here, you can't. The physical differences are few and all but imperceptible, on the order of fractions of ounces and inches. The main difference is in performance and internal specifications apparently. RegistryKey(RegEdit) 04:25, 7 June 2015 (UTC)


 * The physical difference are perceptible if you know what to look for. Just look at .  — Preceding unsigned comment added by Llaanngg (talk • contribs) 13:32, 7 June 2015 (UTC)


 * ...they can though simply look up the model number engraved at the at the back of the phone. See details here. Abecedare (talk) 04:44, 7 June 2015 (UTC)


 * The underlying question is not the difference between a 4 and a 4s, but what is on the default desktop of those models. I posted the person's question as it was relayed, but what is really being looked for is whether a certain app comes by default on the desktop of the 4s.  So the best solution would be a link to an image displaying the default desktop.  I did a search for iphone 4s desktop, but i get all sorts of images I can't personally identify.  Basically this is a request for the reverse of an id request.  Can someone who knows the item provide a link to an image of it.  Sorry this is so complicated. μηδείς (talk) 05:33, 7 June 2015 (UTC)
 * Oh I see. You can get an idea of what the 4 and 4s default desktops look(ed) like on youtube "unpackin"g videos (eg 4, 4S). The default screen thoigh may differ by region, carrier, or due to subsequent OS upgrades (somebody else may know that for sure). Hope that helps. Abecedare (talk) 07:24, 7 June 2015 (UTC)
 * Thanks. The phone is being bought used in the US by a relative and taken to another country.  I'll look at the video.  I have asked the OP to clarify the question, since I think there's a general curiosity, but a desire specifically to know if one or two essential (for the OP's intentions) apps are present. μηδείς (talk) 17:00, 7 June 2015 (UTC)
 * The OP says thanks, the 4s video helped. μηδείς (talk) 18:27, 7 June 2015 (UTC)

X BitMap images


Why would this file be 4.72 KB in size? It's only 16 × 7 pixels, and with a file format that's black-and-white only, you'd only need 112 bits to store the pixel contents themselves. Would it really require 4.71 kilobytes of metadata? The article's "Format" section explains that the format produces lots more data than just the pixel contents would require, but the sample text in that section appears to code 14 pixels, and if you multiply the entire thing by eight (to get 112 bits for the image shown here) it's still only 1,096 characters.

 * The XBM data for that is given in text in the X BitMap article. That 4.72 appears to be the internal memory used by Gimp to represent the image, which includes things like undo information. If I open the image and then set and unset a pixel a few times, that number bumps up. But the exported XBM file, which doesn't have that stuff, is still 150 bytes or so. 87.115.129.187 (talk) 22:02, 7 June 2015 (UTC)
