As we reported two weeks ago, Apple’s annual Back to School promotion will begin tomorrow, according to sources. The program will be similar to last year’s offering, which provided $100 Mac App Store gift cards alongside Mac purchases and $50 cards with iPhone and iPad purchases. Apple will be re-decorating its stores overnight with a new education theme to go along with the new promotion. Earlier today, Apple unveiled upcoming iTunes U updates for the iPad, and the timing seems like anything but a coincidence.
