Hello everyone, I just got a jailbroken iPhone that works with T mobile but my edge doesn't work, i do have the internet plan with t-mobile but still it doesn't work, my firmware is 1.1.1 and I have not updated since they told me not to. If I download this file, Download iBrickr,
would this lock my phone? any ideas on how to get to work?
