I have T Mobile and currently I am using T Mobile Dash phone and I have unlimited texting. I don't need data plan and don't plan to get it for another 6 months. My question is if I buy the G2, will I be able to put my non-data plan SIM card in it and start the phone? I know the G1 requires a google account before you can even start using the phone. Is it like that for the G2?
