Hi all,
I have an iphone 2g running 1.1.4 firmware unlocked and jailbroken with ziphone.
I really want to upgrade to the new firmware using PWNAGE but I don't wanna mess up my phone
I have never unlocked or jailbroken b4, it was done by someone else.
can someone please let me know how i can go about doing this safely?
what do I need to do and download before I upgrade and after?
also. is it possible to have all my info carried over? (i.e, contacts, apps, etc,)
advice would be greatly appreciated!

*another note, is it worthwhile to get the new iphone 3g even after upgrading to 2.0??
