Hi. Newbie here.

I just got a used iPhone from a friend who just bought the iPhone 3G.
I am a current At&t subscriber for almost 2 years and I wanted to use the phone without the additional cost for data.
I know it sounds ridiculous but I'm just a student, unemployed and cutting cost.
I have unlimited text message and about 1500 minutes.

I think I might have heard about jailbreaking/unlocking iPhone from another friend who bought one on ebay.
Basically told me that all he did was insert the Tmobile sim and used the phone without additional cost.
He can surf the safari and just had the iPhone working perfectly.
I am wondering if that is possible on me.

I looked around here and I am so lost I decided to start a thread.
I am using my Windows Vista 32 bit laptop (because my XP desktop wont recognize the phone)
I plugged the iPhone and Itunes it says...

Capacity: 7.08 GB
Software Version: 2.0


Thanks for your advice!!!

therres an app in cyndia that has a hack for tmobile t-zones so the iphone can use tmobile internet
