As T-Mobile prepares to launch the iPhone 5c and iPhone 5s, their retail stores are preparing for early morning sales. An “All Hands” schedule is already in affect for the weekend, but T-Mobile has notified their retail employees that stores will open two hours early, 8am local time on September 20th. Store hours will return to their regular schedule the following day. T-Mobile expects to sell out quickly and will “leverage direct ship to make sure all customers have access to the product as soon as its available.”

While the iPhone 5c has been up for pre-order since last Friday, inventory for the iPhone 5s is expected to move quickly. Anyone looking to grab a unit is best served arriving early, waiting in any potential line and hoping for the best.

Just to recap: T-Mobile will launch the iPhone 5c and iPhone 5s in both 16GB, 32GB and 64GB flavors this Friday. The iPhone 5c will cost $0 down and 24 monthly payments of $22 per month for a total of $528 over two years. The iPhone 5s will arrive at $99 down and 24 monthly payments of $22.91 per month for a total cost of $648.84 for the 16GB variant.
