Apple web application lets you track iPhone availability

The Apple retail availability tracker allows iPhone seekers to select their state of residence and will then display a list of Apple retail stores with iPhone availability indicators. A green dot next your local Apple store means iPhones are in stock while a red dot will indicate a sell-out.

Unfortunately, Apple only plans to update the tracker on a nightly basis. Therefore, shoppers may want to supplement the information available on the site by placing a call to their local Apple stores just before making the trip.

A separate section of the same website also informs iPhone shoppers on how to "get the most out of iPhone," offering a list of free workshops covering the basics and beyond.

Additionally, the Cupertino-based company notes that its One to One members will have access to private tutorials on everything from how to sync their iPhone with iTunes, to sending and receiving email and searching the web.

Reservations for One to One tutorials can be made up to 14 days in advance.
