That’s it. Game over. The US has finally been graced with the “ holy grail ” of the smartphones with AT&T’s launch of the AT&T Tilt today. Just as we expected yesterday , today is the day that HTC Kaiser fans rejoice with the AT&T-branded version of one of the most highly-anticipated smartphones this year. Of course, real fans will already have imported a E uropean HTC Kaiser TyTn II , but those of you looking to save a few hundred off the asking price will want to make the trek to your nearest AT&T store for that brand-new AT&T Tilt. We’re hearing that some stores already have AT&T Tilt stock, but official sales will start tomorrow. We can’t wait to check out the AT&T Tilt with its chromed-out buttons, PTT, and AT&T specific homescreen customizations. Not to mention the 400Mhz processor, 3 megapixel autofocus camera, 3G HSDPA and HSUPA (it’s in there, we just have to wait for AT&T to roll out its HSUPA network upgrades ), GPS (fully-functional), WiFi, stereo Bluetooth, micrSDHC, QWERTY keyboard, and that glorious 2.8 inch touchscreen with the nifty tilt function. Once AT&T gets its HSUPA infrastructure out the door, we’ll be zipping along, up and down, at broadband speeds on our AT&T Tilt. A trip to your AT&T store and $299.99 will put an AT&T Tilt in your pocket come tomorrow. You already saved up for this beauty, didn’t you? You’ll find us at the AT&T store tomorrow, see you there!
