Giant Apple iPhone Displays at Apple Stores

It appears that Apple iPhone displays are going up at Apple Stores. TUAW notes that a “large, covered rectangular display” appeared at the 5th Avenue Apple Store tonight.
They’ve also posted a small gallery of images of the shrouded display. Apple Store employees were reportedly unable to give out any further information.
We’d heard rumors that Apple Stores would be getting more promotional displays this Friday, and there had been hopes (though unconfirmed) that iPhone rate plans details would also be announced at that time.
