I have a 1.1.3 OTB phone, which I downgraded to 1.1.1 and jailbroke successfully. I have service working on tmobile with Gunlock - OneClick from Sendowski.de repository, as well as the Bricktool/SignalFix from the same source.

The problem I am having still is that if I reboot the phone, I have to reinstall the Gunlock and reinstall bricktool, or the phone simple will not get a signal. I have tried time after time, but its always the same, not until I reinstall both does it work. I have also tried manually installing bricker, and no difference.

So I am thinking I want to either try moving to 1.1.2 or else just starting off again the way my phone was originally and starting over.

So how would I safely go from what I have now to the same way the phone was when I pulled it out of the box a few days ago? Do I just upgrade to 1.1.3 in itunes?

There are so many threads and so many guides and I have read for hours, and am just thoroughly lost.
