I'm relatively new to the smartphone area and therefore please pardon the faults in the information that i have. I'd like to know if the I-Phone can be unlocked as in can it be used with providers like BSNL, Vodafone down here in India ? I've heard purchasing the phone on a contract basis or something but dunno much about it. Also the Samsung galaxy Epic 4G has been released by Sprint . Does it mean that the phone will be available only to U.S Customers ?? What about ppl in other countries(India in my case)?
