Sensation or the similarly specced Galaxy S II from Samsung. Of course, neither of those is actually out in the US yet, so if patience is not your favorite virtue, T-Mobile just made that decision for you. The carrier has announced it'll start selling the HTC Sensation 4G from June 12th at Walmart stores, after which it'll be "exclusively" available on June 15th from T-Mobile retail stores. Pricing is your typical $200 on a two-year contract after a $50 mail-in rebate. Samsung's superphone shouldn't be too far behind, but it does look like T-Mo subscribers will get a good few weeks to familiarize themselves with Sense 3.0 before having to hear any gloating about Super AMOLED Plus displays and 8.49mm slimness. PR after the break.
