in this post ill show you how to get past the 4.0 beta udid activation for all devices (found by me)
*notes* if you rely on a soft unlock (blacksn0w, ultrasn0w) DO NOT UPGRADE YOU WILL LOOSE YOUR UNLOCK AND CANT GET IT BACK.
i will also show you how to downgrade back to 3.1.3
if your jailbroken you can always rejailbreak with sprit.
you will need to restore.
i do not know the status of upgrading on windows.
you need to find the 4.0 ipsw on your own unless a mod tells me i can put it in the op.
*/notes*
ok so you need to sign up at this site
you will put in your udid. after this your udid will be in apples servers and since apple doesnt separate beta firmware and beta apps udids you can get the beta.
keep in mind. i do not know if you need to sign up for a beta before hand. if you guys all get the same results ill update the op.
now plug in your device and open itunes. hold alt (shift on windows) and click restore. then click on the 4.0 beta firmware. you may need to put it into dfu mode if it doesnt work.
*how to downgrade*
download a 3.1.3
plug in idevice and open itunes
hold alt (shift on windows) and hit restore. choose the 3.1.3 file
you may need to put it into dfu mode.
around the end of the restore you may get an error like 1015. dont worry it's all good.
download this
now open the folder and open the rslite command prompt.
type this
[Recovery] setenv auto-boot true
[Recovery] saveenv
[Recovery] reboot
*[Recovery] will be there on its own*
Please remember this is beta software and im not responsible for harm or damage you may do to your device
