Probably not $350 US
Good cell phones like a 3 band Nokia are under RD$3000 in Orange shops, so less than US$100. Why anyone would spend the equivalent of RD$10,000 on a cell phone is beyond me.
You can now get a good basic Motorola for RD$890 and a basic Mitsubishi for RD$990. A phoneis a phone. It isn't a camera, or MP3 player. (They can be just mediocre versions of these devices)
Save your dough. Buy one here within a sensible price range.
