  • Restore to 4.2.1

  • Install SAM deactivate and wildcard activate connect to iTunes
  • Install ultrasn0w and unlock...
  • Make call... Working on Vodafone sim

Push notification not working anybody have any idea what to do???

What carrier are you using? I think you need to alter your APN settings to make sure Push notifications work properly.

Hey mate, I didn't understand this :

Install Cydia and activate using redsn0w 0.9.6rc8 (factory activated) and Install ultrasn0w and unlock...

How are you able to unlock using ultrasn0w for unsupported baseband on 4.2.1? I bought iPhone 4 from BestBuy (AT&T locked) and got it to India. I'm waiting for the unlock for the baseband 03.10.01 . It came with 4.2.1 pre-installed.

He has an AT&T iPhone 4 that was bought before iOS 4.1 was released. The baseband on that is 1.59.00 and is unlockable with ultrasnow. All other AT&T iPhone 4's with iOS 4.1 upwards have the locked basebands (2.10.04 and 3.10.01). There is no way to downgrade the baseband to 1.59.00.

Just like @fliypx said. I got baseband 1.59.00

He said restore to 4.2.1

Doesn't that mean the BB upgrades to 3.10.01?

Its worth mentioning that its possible to upgrade iPhone 4 FW without upgrading baseband using TinyUmbrella as described here:

For other devices, you need to use a custom FW from which the baseband update part is removed.
