In many areas, one of the biggest issues that T-Mobile suffers from is that it lacks retail stores where users can walk in, check out their devices, and buy. In my area, there is only one tiny T-Mobile store for potential customers to shop at.

T-Mobile and RadioShack have announced a new retail agreement that will have RadioShack’s 4,000 retail locations offering T-Mobile phones and service. That number will just about double the retail presence of T-Mobile.

RadioShack will be offering high-end devices like the G1 and the myTouch 3G along with some other devices from T-Mobile. The terms of the agreement were not disclosed and the devices will hit RadioShack locations later this summer.
