T-Mobile is certainly looking to take this Smartphone BOGO and ride it all the way to the bank. They have again extended the offer, this time through June 20th. Currently, the Garminfone and HTC HD2 are only available as the first phone and cannot be used as the free device. The myTouch Slide will release under the same guidelines, however, after Jun 16th, it can be used for both the first AND second phone. While there is a chance T-Mobile may again extend this offer, its high time you take advantage of it if you already haven’t, it won’t last forever you know!
