The Motorola Defy is not only impervious to water, sand, and good old fashioned brute force (within reason obviously), but it is also apparently not the slightest bit phased by Motorola’s own unwillingness to keep the updates coming. When the device isn’t scuba diving or spelunking, chances are that it’s kicking back and enjoying one of the latest versions of Android, all the way up to 4.2 in the form of an unofficial version of CM10.1 thanks to XDA Recognised Developer Quarx.
Now this is very much an alpha version and really not suitable for daily use. However, it certainly proves that 4.2 isn’t out for the question for this plucky little device. You’ll be able to boot up and swipe around, make calls and send texts. A lot of the basic functionality is there. However, there are obviously going to be quite a few bugs, and some of them are fairly annoying. You may find your SD card not recognized, WiFi needs to be connected manually, camera/video recording is not fully functional, and neither are the device’s USB capabilities. All in all though, a promising start for 4.2 on the Defy
If you would like to try this version of CM10.1 for yourself, check out the original development thread for more info._________
