Also, I was able to downgrade from the 3.0 Beta to 2.2.1. Took me a few days to do so. I'll put how. It is pretty easy:<BR/>1) open itunes<BR/>2) get iphone in DFU mode<BR/>3) select restore iphone (using the original 2.2.1 firmware, not the custom one)<BR/>4) let iphone do the restart process until you get ERROR 1013<BR/>5) close itunes<BR/>6) open quickpwn. you will get a message saying to hold power and home for 15 seconds. do it exactly like that hold the power and home for 15 secs.<BR/>7) turn on iphone by holding power button for 2 secs<BR/>8) open itunes and iphone is recognize and activatedxLiL' Sm0K3x ProduCtionzhttp://www.blogger.com/profile/08118890088418146305noreply@blogger.comtag:blogger.com,1999:blog-8026726330557031.post-13213134496203937412009-03-19T07:38:00.000-07:002009-03-19T07:38:00.000-07:003.0 software can be UPGRADED via iTunes, not RESTORED as from that point, You will lock device without activation and will not be usable until You register on developers program @apple web site.<BR/>Downgrade IS possible by turning device in DFU mode and restoring even original or whatever software You have.<BR/>Cheers, FergyRamonhttp://www.blogger.com/profile/10090877400305145056noreply@blogger.comtag:blogger.com,1999:blog-8026726330557031.post-11637357048949581612009-03-18T12:18:00.000-07:002009-03-18T12:18:00.000-07:00Thanks tech<BR/><BR/>I already restore my iPhone 3G Unlocked with 3.0 beta.

But remember that you can't downgrade according to Apple's advisory.<BR/><BR/>"By installing iPhone OS 3.0 beta software on your Authorized Test Devices, these Devices are permanently "locked" into testing mode and cannot be restored to earlier versions of iPhone OS."techhttp://tech.element77.com/noreply@blogger.comtag:blogger.com,1999:blog-8026726330557031.post-41508955140296995602009-03-18T07:16:00.000-07:002009-03-18T07:16:00.000-07:00If I'm not iPhone Developer member, can I activate my iPhone 3G with iTunes after restore this 3.0 beta?<BR/><BR/>Thank you.Anonymousnoreply@blogger.com
