Okay. I am going to buy the new upcoming Sony Ericsson Z780a unlocked, but I dont know what service I want it for. I live in Washington DC but my mom and I travel to NC alot. And next year my friend and I plan to visit Japan and S. Korea after graduation. Due to the fact that these countries don't have GSM, I need a service that will let me roam onto other services over there(So happy that the Z780a has UMTS ^^). I'm thinking AT&T but I'm still not sure. So what should I choose? Thanks in advance! ^^
PS: I also need a service that lets me use my phone in the subway, has free nights and weekends, and free internet.
