Hi, I received my locked G1 yesterday and right away bought an unlock code, I received the code today and I unlocked my phone to the AT&T network. I have already activated it. *However, I don't have a data plan for AT&T, I can only make and receive calls and text. How can I make sure that data is turned off so to not incur charges for data? I don't want a really high bill. I want to be able to use internet on wi-fi because it is pretty much everywhere and it is free. *I turned off data roaming and auto sync, am I ok now? just trying to make sure. Thanks for your help.
