Android 4.1 Jelly Bean comes with lot of features such as improved notification bar, smart keyboard, offline voice typing, new camera app etc. That’s why everyone wants to run this latest update on their devices. But as you might have heard that Jelly Bean update will not be rolling out for all the Android devices. But being open source to developers, Android can be modded & ported in the form of custom ROM to any other device which isn’t getting JB update. Even if you’ve owned Samsung Infuse 4G, you can upgrade its firmware to Jelly bean via Cyanogenmod. Thanks to XDA senior memberscott.hart.bti who has ported & released Cyanogenmod 10 unofficially for AT&T Infuse 4G. According to him, almost everything is working which works in ICS. Since the ROM is still under development, it might contain some bugs (like GPS, which can be laggy for this particular release) But don’t worry, it will be fixed soon as development goes on.
