How to upgrade to Iphone 3.13?
Hi,
Today I was upgrading my iphone OS from 3.12 to 3.13
I downloaded newest itunes as instructed and now they only offer me to upgrade to 4.0 which I don’t want
I manage to download 3.13 ipsw(?) file but no idea how to use it
I know 4.0 is newer and maybe better but I want to stick to 3.13 until 4.0 is proved to be reliable
any tip on what I should do?
Using Fluther
or
