I generally tend not to print these web-only sales on T-Mobile.com anymore as they so frequent it’s hard to keep up. I’d recommend checking out T-Mobile’s website every day if you’re looking for a special offer. In any case, todays special offer is on the HTC Sensation 4G, now free for new customers and add-a-lines. The web-only deal runs through May 3rd, though it coincides with T-Mobile’s ongoing trade-in offer which could allow you to make a profit and pick up a brand new smartphone. The Sensation 4G may be a little older compared to the HTC One S, but assuming our June timeframe comes through the Sensation 4G will be reborn with Ice Cream Sandwich.
