I have an iPhone 4, s/w version: 4.3.2 and have been out of touch with what's new in hacking terms.
My provider is Rogers and when I'm traveling to Europe I use a Givey device to use it with another provider but I miss the nice interraction that I could have between with a MAC and a iPhone, but that is only when using iOS 5.
If I want it to upgrade to iOS 5 or 5.1, is it feasible? Is there a guide and what are the pros and cons please?
I have seen some websites that is possible if you pay some money, or is it a trick like in the past?
