Blacksn0w to Unlock iPhone OS 3.1.3 baseband 05.11.07

He has also posted reason why blacksn0w is failing to unlock iPhone 3.1.3 since it searches for function to patch by searching the binary for a reference to string “SIM is not supported”. In iPhone OS 3.1.3, Apple has replaced the same function in a way that it now uses the string “Verified”.

Since the location to patch is determined by instruction search&replace, the said patch still works in iPhone 3.1.3 after changing the string and its length in Blacksn0w binary.
