Sprint has started allowing customers to pre-order the 8GB iPhone 4 in either black or white flavors for $99.99. Sprint will also begin pre-orders for the new iPhone 4S starting tomorrow, likely at 12:01am PDT.

According to the description on Sprint's website, pre-orders will be available "while supplies last" and will ship to customers by the 14th or 15th of October. Customers planning to pre-order may want to head over to their website to secure their order in case supplies run dry.

Sprint will still offer iPhone customers unlimited data with plans starting at $69.99, and this may have some impact on new iPhone users trying to decide on a carrier, given the likes of AT&T and Verizon no longer offer unlimited data plans.

Will you be pre-ordering your next iPhone from Sprint?
