Sherif Hashim has confirmed that his baseband crash is working on both iPhone 4 basebands 2.10.04 And 3.10.01 when replying to a query on twitter.
iPhone Dev team is waiting for Apple to release the iOS 4.3 before releasing the iPhone 4 unlock and now since the firmware release is imminent expect the updated ultrasn0w to unlock iPhone 4 soon.
However, unlock for the baseband 3.10.01 and 2.10.04 will not come immediately after iOS 4.3 release, as the Dev Team will test the tool with the new firmware before releasing it to the general users.
