Remember last week when AndroidCentral managed to get a hold of some info on a potential new Android device for AT&T, the HTC Liberty? If you were overwhelmed by the news of Apple's iPhone 4 announcement and didn't get the memo, you may be interested to see what Engadget dug up today - courtesy of YouTube. Apparently AT&T Labs has a pretty thorough testing process that they put phones through before becoming market-ready. I'm guessing they're proud of the process, else they wouldn't have posted a video of it on the interwebs. The only problem, if you want to call it that, is that the video contains images of a device that has yet to be announced, and certainly not released. That device, according to Engadget, is very likely the HTC Liberty, and it appears to be running HTCs Sense UI. The shot of the phone is more like a cameo really, but feel free to make that decision for yourself. Any of you want to put the Liberty through your own testing? Let us know!
