T-Mobile really wants you to know that its 4G network is the fastest one out there. In fact, the carrier is willing to give you a cool 1,000 bucks if you can prove them otherwise. That’s confidence right there. During this weekend, you can bring your iPhone to a T-Mobile store in the Seattle area and have it compete against a Galaxy S 4G. If your iPhone wins –very unlikely — T-Mobile will give you $1,000. If the Galaxy S 4G wins, T-Mobile will be kind enough to give you $300 to trade in your iPhone for a Galaxy S 4G — how nice of them.

If you live in the Seattle area and are feeling a bit adventurous this weekend, you can follow this link for participating stores’ location. We wonder how long T-Mobile will keep up this marketing tactics now that AT&T is buying the company.
