Upgrading the Galaxy S2 Skyrocket I727 to Jelly Bean via Slim Bean ROM

Sometimes, we just want a device that can be as fast, simple, and reliable as possible. The Slim Bean ROM, known for its lightweight file size and overall performance, has been recently released for the AT&T Samsung Galaxy S2 Skyrocket SGH-I727.
Released by XDA Developers member gmillz, this particular ROM has the extra clutter of apps removed and its essential apps modded to make it run smoother and lighter. This ROM’s overall optimized and simple approach to everything is a beast when coupled with the speed enhancements and larger displays added into the Galaxy S2′s AT&T variant, the Galaxy S2 Skyrocket.
