A source in retail just sent us some artwork from upcoming Apple Store frontage that confirms that Apple retail stores will open at an early 8am to begin selling the third-generation iPad. Earlier, we had heard that a new Houston store would be opening at 8am on the 16th, and this strongly hinted at a morning iPad launch.

Additionally, we’re hearing that there is a major overnight for retail employees on Thursday, and all available hands will be on deck Friday morning for the new product launch. As a bonus, those retail employees who are working outside of normal store hours will be receiving an additional 10% wage increase for their time.
