I still have not moved from 2.1 to 2.2, but the temptation is there with the promise of a better browser for javascript sites..<\/p>\n
I saw this as a comment to another post.. I have not tried it but when I read it the steps seems fine.\u00a0 Try at your own risk, but if your phone is already messed up, then the risk is low isn’t it?<\/p>\n
Here is a direct link to the comment (no.7).<\/a><\/p>\n I spend a full day trying to recovery my iPhone after upgrading it to 2.2 and finally I was able to go back to 2.1. <\/em><\/p>\n So I decided to share it with all impatient morons \u201clike me\u201d in the world; who upgraded their iPhone 3G to 2.2 and lost their unlocked capability; here is the resolution:<\/em><\/p>\n 1- Download the iPhone 2.1 firmware from: http:\/\/www.spaziocellulare.com\/ispazio\/download-firmwares-iphone-3g\/<\/a> 5- From iTunes; Restore to iPhone firmware 2.1. Hold down \u201cShift\u201d button and press the Restore button at the same time.
\n2- Download QuickPwn21-1 from: http:\/\/thepiratebay.org\/user\/iphonedev\/<\/a>
\n3- Connect your iphone to your computer and turn it OFF
\n4- Restart your iphone in recovery by following these steps:
\n\u2022 Connect your iPhone to your computer
\n\u2022 Turn iPhone off
\n\u2022 Hold power and home together for 10 seconds (exactly)
\n\u2022 Release power but keep holding home until the computers beeps (observed on a PC) as a USB device is recognized.
\n\u2022 At no point will the display come on. Now your restore should work.<\/em><\/p>\n
\n6- Choose the iphone 2.1 firmware you just downloaded in Step 1.
\n7- Wait till it finish. You will get one of the following errors: 1011, 1013, 1015, you can ignore them.
\n8- Your iPhone is restored back to Firmware 2.1. Now close iTunes
\n9- Unlock your iPhone using QuickPwn for iPhone ver 2.1.<\/em><\/p>\n
