Roger that...I'm a big fan of Motorola hardware, and I'm regretting buying an HTC. However At&t doesn't sell the Electrify...I saw on the Moto site that it was being sold "unlocked"/"non-carrier branded", and having both CDMA radios as well as GSM. My co-worker has the Sprint braned "Proton", however when I installed my AT&T SIM card, the GSM radios did not work. The Sprint version may be locked much like the Verizon Droid Pro(s), in that US GSM carriers are blocked, and the pre-installed Vodafone SIM only works internationally.
