diegoooo82 - I stand by my original advice - if you need a firmware update, get it from your provider. Yes, it can be hacked, but unless you understand the directions given here you're best off not doing that.
Who said anything about international? He said he's Italian, he did not say he lives in Italy. He said Tmobile, which is USA, not tmobile UK, additionally, I have successfully loaded Cingular Software on TMOBILE UK, VODAFONE Netherlands, Bharti and many other Euro and Asian branded, and used systems...Guess what? They all work perfectly?
I would love to know what MODIFICATIONS you speak of, because if you are talking about the phone having to be unlocked to use software from another carrier. YOU ARE 100% WRONG
