RadioShack and T-Mobile USA have announced that they have a new retail agreement in place that will allow RadioShack to offer T-Mobile products in its 4,000 nationwide stores. The agreement will start later this summer and RadioShack will have hot new devices like the G1 and myTouch 3G.

The new arrangement nearly doubles the number of retail outlets for T-Mobile making RadioShack the largest retail partner for the mobile company. The terms of the agreement were not disclosed.

Doug Chartier, senior vice president of sales at T-Mobile USA, said, “Through our milestone partnership with RadioShack, T-Mobile’s presence in national retail stores expands nearly twofold, giving millions more people the opportunity to readily access our products and take advantage of the tremendous value T-Mobile provides its customers. By combining T-Mobile’s innovative devices and great value with RadioShack’s knowledgeable sales representatives, we expect customers to have an excellent in-store experience.”
