In a move that smacks convention right in the face with the back of its hand, T-Mobile has raised the prices of two old smartphones. Rumors of such a move have been circulating for a while but logic and reason made it hard for us to believe such a move would ever be carried out. But alas. The gray-haired T-Mobile myTouch 4G and T-Mobile G2 have both been bumped from $199.99 to $249.99 on contract. $250 is a steep price for last year’s gear, especially considering how fast Android evolves. We’re now looking at dual-core demons and T-Mobile wants a premium for old wares? Luckily, some other phones have seen price adjustments in the proper direction, including the myTouch 3G Slide ($99.99), the Samsung Gravity T ($29.99), the Gravity 3 ($19.99) and the Smiley (free).
