Sure it’s no HTC Dream, but if you happen to live in one of T-Mobile’s emerging 3G markets you might be interested in taking a look at the first Sony Ericsson on T-Mobile in a while. This flip phone isn’t going to win any awards for innovation, but if 3G data, GPS with TeleNav support, 2 megapixel camera, Bluetooth, and more is your cup of tea, then the TM506 might be worthy of a gander. While already announced, it’s available today for the bargain basement price of $79.99 after a 2-year service agreement and $50 mail-in rebate. Anyone running down to their local T-Mo shop?
