Hello guys. First of all, let me just tell you that currently my iPhone's version is 3.1 (7C144). So I googled about this in order to find ways to unlock my iPhone and I found this http://www.unlock-the-iphone.com/. I recklessly bought the software which turned out to be a total BS since it hasn't released its 3.1 version yet. So I advice to you guys to not trust the software atm. And then I visited here when I found out someone just posted PwnageTool 3.1. I downloaded and tried it, and now I have Cydia and Icy in my iPhone. The problem is I still can't use it to make calls and stuff like that since I'm using different carrier. Could someone please tell me on how to unlock it or use Cydia?? Thanks.
