Apple has just released the first beta version of the latest edition of their iOS mobile platform to all registered developers. Available for the iPhone 4S, 4 and 3GS, the iPad and iPad 2 as well as the third and fourth-generation iPod touch devices, this is hardly the most major of updates.
iOS 5.1 focuses mostly on giving developers more APIs to work with and bugfixes. What might be more interesting to you than the update itself is the code of the new iOS release, which references three new iDevices.
iOS 5.1 mentions the yet unseen iPad 2,4 (which might be the Sprint version of the iPad 2) and iPad 3,3. The latter joins the previously referenced iPad 3,1 and 3,3, which will probably be the different versions next iPad, which should be announced in March 2012.
The iPhone 5 also makes a first appearance in the iOS code with version 5.1. Of course, we can’t give you any information about the specs of either of the upcoming devices at this point, but further details about them should start pouring in soon enough.
