This weekend is already looking pretty interesting because apparently T-mobile has a pretty serious bet going on. According to a banner posted on the site, T-mobile will pay $1000 to anyone in the Seattle area that has an iPhone (Verizon, or AT&T) that can prove to them their phone is faster than the new Galaxy S 4G. They say any third party speed test application will work, and itís best out of 3, so you have 3 chances to win this.
If you do win, T-mobile will either just give you a thousand dollars or $300 to trade in your iPhone for the new Samsung device. The stores that will work with you are on the poster and more information is available at the source link, enjoy.
