I love this phone. It does have a common problem though. Both my gf and myself are using this phone (hers is AD, mine is AP). Both phones got "insert sim card" error after a few months. Sent mine to the shop, they said it was a faulty sim card holder. Problem fixed, but after that I don't have 3G anymore for some reason dunno whether it is a phone problem or the shop f@#$ it up.
