ok, i downloaded iPhone1,2_3.1.3_7E18_Restore.ipsw from here: www iclarified.com/entry/index.php?enid=750
then i installed it on my iphone 3g and used RECBOOT to make it work.
I now have a - by default unlocked - iphone 3g with OS 3.1.3 from the above link.
I know wanted to jailbreak this with Pwnage Tool 3.1.5 but the tool cannot find the Firmware and if i select it myself it says it cannot be recognized.
i noticed that the 3.1.3 firmware from the screenshots for pwnage tool had a different name than the one i downloaded and installed..?
-should i even downgrade and jailbreak the os 3.1.3 or would 3.1.2 be a better choice?
-why didn't it work with pwnage tool?
-should i use redsn0w?
thanks a lot!
