Communication store in Pac Mall, ask for Waldo. He's not there right now, doing a buy in HK. He's going to be back after October 25th.
I don't know if he can modd your phone, but from what I've seen he's pretty knowledgeable and have modded many different types of phone.
If he can't he will tell you that and not even try, because he doesn't want to do "bad" jobs and get a "bad" rep.
