The Samsung Galaxy S2, together with its other variants, has been seeing a lot of custom Jelly Bean ROMs for quite a while now, and this time, its LTE variant on AT&T, the Samsung Galaxy S2 Skyrocket SGH-I727, has just received a brand new ROM reported to be a lite version of everyone's favorite CyanogenMod 10 ROM. The new ROM is only compatible with the AT&T Samsung Galaxy S2 SGH-I727 and features a unique twist to that familiar Jelly Bean flavor that we have fallen in love with.
The lite version of CyanogenMod 10, aptly named Superlite CM10 Jelly Bean ROM, focuses on giving the Galaxy S2 Skyrocket better battery life. It's light weight because the developer has removed unwanted bloatware applications to give it lightning-fast performance, improved notifications, smart keyboard, Google Search with voice recognition, and a dozen more features. If you are looking for a fast-performing ROM without the excess baggage, then this ROM might be perfect for you.

But, he keeps himself up to date, so now he has a dual-core beast in his pocket, and is looking forward to getting his first quad-core monster, and when it comes, his first eight-core phone. Perhaps he should be called Mr. X-Core, where "X" equals the number of CPU cores.
