Hi everyone, I will be going to the US for 5 months in January, exchange semester at Cornell University. I have a (factory) unlocked iPhone 3GS, can put any SIM card in it. During my time in the US I'd like to get a local phone number, e.g. I would buy a prepaid card of some sort from one of the carriers. Question: Does anyone have some advice on what is the best option for that and which carrier offers some prepaid data packages? Like 50MB for 10$ per month or stuff like that? Thanks for your help.
