MacRumors says they are recieving several reports from their sources claiming that Apple is ready to debut their official retail store application for all iOS devices.

"Apple is planning to launch a new iOS application tomorrow that will offer customers access to the company's online store and iPhone pre-ordering, as well as the ability to book Genius Bar appointments at brick-and-mortar retail stores."

MacRumors also claims to have gotten word from a customer who emailed Steve Jobs last month regarding the possibility of an iPhone-friendly online Apple Store and received a reply of "Coming soon" from Jobs. This is one of those applications that we figured to have seen in the App Store long ago but with iPhone 4 pre-orders taking place tomorrow, the timing seems perfect.
