Optimized stock ATT-based ROMs for US based version of Samsung Galaxy S III make this phone an Android dream machine. Its large enough to compete with Nexus 7 in size. Its a phone with 4G connection and is super responsive. It will have 4.1 update either from official or custom ROM developers in the near future. Beta is out already. US version is supposedly slightly superior to thr international one, but I never tried the intertional version. This one is absolutely awesome!
