Android 4.1 Jelly Bean is on everyone's lips and with good reason. The update brings a number of features and enhancements, such as a smoother interface, advanced search functionality, Google Now for automated information, a better Android keyboard, and an improved notification menu.

Unfortunately, this update might not make it to all Android devices, but thanks to the hardworking folks at XDA Developers, almost everyone can get a taste of the update, including Samsung Infuse 4G SGH-I997 users. You can thank developer scott.hart.bti for bringing the unofficial CyanogenMod 10 to your devices.

Almost everything that works in Ice Cream Sandwich works in this ROM, but there are still a few issues that the developers are working out, such as the GPS being laggy or freezing when it is used and Project Butter being uncooperative. Rest assured that the developers are hard at work, so these issues should be fixed in no time.
