After reading as many of the "mobile data in the US" threads as I could on GZ, I landed and went straight into an AT&T outlet this morning to get a prepaid micro-SIM. I was told that AT&T do not sell prepaid SIMs which work for mobile data with the iPhone or any other smartphones.
I'm here for two weeks so would like to get local mobile data somehow. Anyone have some recent successes in doing so? (I'm currently in LA)
