Want to make sure you get the T-Mobile Samsung Vibrant on launch day, just in case it’s sold out? Well, beginning July 1st, customers can pre-order the Samsung Vibrant at any RadioShack store. But here’s the catch, to pre-order, customers must purchase a $50 gift card, which will be applied toward the retail price of the device. You will then be able to schedule an appointment to pick up and activate your Vibrant at RadioShack stores with anticipated availability starting July 21. Customers who pre-order at RadioShack will receive a $50 gift card by mail after purchasing their phone with qualifying voice and data plan on a two-year contract. Additionally, you can also pre-order online at http://www.radioshack.com/vibrant beginning July 1.
