there is a lot of misinformation in this thread.
1. you either have unlimited data or you dont.
it is possible to not have data, you have att block the data on your account, then you can only use the wifi.
2. the original 2g iphone can be found for 150-200$. not ridiculous amounts.
3. you don't have to jailbreak or unlock
I have a 2G that is not activated and I want to add it to my existing AT&T account as a new line without a data plan. I have another phone that has a simm that I can use to add the line to account with AT&T and then switch the simm to the Iphone after I put data block on. My question is how does one activate an Iphone without getting tagged with a data plan? I called AT&T CS and talked to them and they insisted that I had to have a data plan with a 2G Iphone.
