sorry m8 there is no link but any way the iphone unlock software has not been released as yet the software that is about only lets you use the phone as an expensive ipod without being on the AT&T network.
I got an Iphone off my bro in law, was locked up (too many pin attempts) he couldn't be bothered calling up, unlocking, all that so I done it for him...looked around net, tried loads of programmes....managed to find a good one, where ya flash a backup image (activated image) where ya dont have to register through itunes...I now have latest firmware on it, jailbroken, and unlocked to any service, only thing is that when ya set it up, you have to reset the service carrier (networks) as it will say no service...after reboot works a treat....only thing is that you can't update it u need to wait on a flash to come out ... but I'm not bothered as long as it works if anyone wants to know this software you could pm me and I'll tell ya, if allowed by mods
after jailbreaking the 3g i phone you have to connect the phone wireless only go to the cydia application and find the yellowsnow application, if its not there then go to manage and type in the app address
* Cydia source: yellowsn0w.com and download and run the application ( it is a zero in sn0w)
QuickPwn for the 2.2.1 firmware is already out
worked fine for me, I did a restore to the 2.2.1 firmware then jailbreak with QuickPwn (not interested in unlocking at the moment as it's a contract) yellowsn0w not working on the updated baseband in 2.2.1
If you do want to unlock and have 2.2.1 update you have to make a custom .ipsw update using PwnageTool
well if you want to keep your cydia apps it's not hard, just have to install AptBackup app. It copies packages to an area of the disk that isn't lost during the update, so you run AptBackup and back them up, do the iTunes backup, do the update, restore from iTunes, jailbreak, reinstall AptBackup, then restore all your apps. Up to personal choice obviously. I used it as an opportunity to wipe all the random apps I had added, and just re-installed stuff I liked.
