I was hoping someone could help me by providing a 'upgrade jailbroken iphone for dummys' kind of response!
I have a UK iphone 3G which I brought to Australia.
Took it to some phone shop where they unlocked them. It has worked since but was told not to upgrade the software because it would lock again.
Think they installed Cydia on there, but i havent a clue what it is or does.
Currently have version 3.0.1 and was wondering if I can upgrade to 4.0.2 in itunes
Is there an easy way of doing it?
Would appreciate any help on this.
