had my Verizon thunderbolt long enough switched to att m8 amazing phone probably better when I figure out all the features...better signal at work snappy as hell battery lasts forever hardest part is getting used to how thin it is I even put a seidio surface case on it still seems thin and hard to get used to after my bolt with extended battery that was way heavier I had the bolt s-off and rooted.. custom rom just might leave this baby alone works super
