I have firmware 1.1.1 (04.01.13_G) on one of the original iPhones. It is jailbroken and anysim was used to unlock it. If it is not unlocked it is almost useless to me.
Now I want to upgrade to version 2.x. Has anyone in here done that and can you recommend an online guide tutorial to follow?
It is a while since I last updated it. What are the pitfalls? If I install a high version that can't work with unlocking can you just revert back to an old version and try to unlock it again?
I am still running iTunes 7.4.2 (on OS X 10.5.7).
EDIT: Will firmware 3.0 work on a non-3G phone? Maybe I should wait for ultrasnow to be released and update to firmware 3.0 with that?
