ok I've jailbroken my phone and went through the process more times then I'd ever like to remember I was on 1.1.4 and was happy but the app store was getting some really cool stuff that I wanted so I decided to upgrade to 2.1 and so I did. But me loving the iPhone for the jailbreaking I wanted to customize my phone and have all my 3rd party apps again along with app store why not have the both of best worlds. I have a mac and windows so I got the newest quickpwn and pwnage tool from dev team blog. So I went along the normal process and created my custom firmware then restored with that and everything worked fantastic awesome go me. DUN DUN DUNNNNNN I have no signal at all so restored it back to normal ok confused. so I tried quickpwn and that seems to work but then just goes to a white screen and doesn't reboot or anything just stays there. so any help would be awesome.
