T-Mobile is betting that its Galaxy S 4G phone is faster than your iPhone, whether it be Verizon on AT&T. They are so confident about it, that they are challenging Seattle area iPhone users to a speed test between Friday, April 29 – Sunday, May 1. All you need to do is bring your iPhone into one of the ten participating T-Mobile stores and beat the Galaxy S 4G out of a speed test, best two out of three. If you win, the network will give you $1000 big ones.
