I would take the SR if you are looking for fast speeds. I believe VZW will be the only US carrier with the 4G LTE Model and I doubt a VZW LTE Nexus will be able to run LTE on AT&T, so SR ftw if you want LTE.
I was only looking @ the SR because i can get it a lot cheaper than the regular GS2 on AT&T. 4G LTE never was a factor for me regarding the choice especially since I dont live in a 4G LTE area.
that said, my GN should be in on Friday (and im at work bahhh )
Anyone that's ordered from Expansys have any input on their shipping tendencies? Also, does this come with a universal charger? Or do I need one of my own?
