Radio Shack will also offer all T-Mobile handsets free on June 19th

T-Mobile's retail locations are going to be an absolute mad house this Saturday thanks to the company's epic one-day sale in which all handsets are free, so it's a good thing that Radio Shack has announced it will be joining in on the fun as well. On June 19th, over 4,000 Radio Shack locations across the U.S. will be offering all T-Mobile handsets for free on new 2-year agreements. The offer is only valid in-store and add-a-line and flex pay customers won't be able to take advantage of the offer, but everyone else should be able to and will receive a $35 activation credit to boot.
