Dear Mate..thank for your reply.
But i heard a lot on rooting, but I know nothing about root...can you explain me how to do that? I need to root before I use titanium backup?
You also mentioned lower resolution..what they means? Do i need to compromise if I did that?
Also after I freeze as your suggested, I can use freely in forwarding call ? or even get connected to GPRS/EDGE when roaming in China since I can't get connected which may be caused by VZ pre-set limitation?
Can I jsut install titanium and freeze as your suggested but not doing anything as your thread you sent, which seems complicated...?
