iPhone 5c Pre-Orders Go Live

Update from 8:29 A.M. to include additional pre-sales information.

NEW YORK (TheStreet) -- Apple's (AAPL) iPhone 5c is now available for pre-order, as the tech giant looks to ramp up sales of its largest revenue driver ahead of the upcoming holiday season. However, people who want Apple's high-end phone, the iPhone 5s, will have to wait.

When making the announcement earlier this week that the 5c would be available for pre-order starting Friday, Apple conspicuously "forgot" to mention when the 5s would be available for pre-order. The iPhone 5s will be available at 12:01 a.m. Sept. 20th for pre-order, but customers will more than lilkely have to line up at Apple Stores and the stores from Apple's carriers, including AT&T (T), Verizon (VZ), Sprint (S) and T-Mobile USA (TMUS). Apple's approach to limiting pre-orders for the 5s ensures there will be exceptionally long lines, as customer demand for the phone is said to be high.

The iPhone 5s has a host of new features to separate it from Apple's previous offerings. Sporting a fingerprint authentication -- TouchID -- on the home button, the 5s also runs a 64-bit A7 CPU, the first 64-bit chip inside a smartphone. Apple also unveiled the M7 co-processor, a chip used to track motion data. The phone comes in silver, graphite and gold, marking the first time Apple has offered the iPhone in colors other than white and black. In contrast, the 5c runs Apple's A6 processor, announced last year as part of the iPhone 5. It will come in five colors (white, pink, yellow, blue and green), and will come in 16 GB and 32 GB models. The 5c starts at $99 on AT&T, Verizon, and Sprint. T-Mobile users can purchase the phone unlocked, which starts at $549 for the 16 GB model. The yellow version of the 5c has already sold out at Sprint on the pre-order, with the carrier's Web site saying it'll do its "best to get it to you by 9/20; but because of high demand, some phones will ship in up to 2 weeks." Apple shares were lower in trading Friday, off 1% to $468.05. --Written by Chris Ciaccia in New York >Contact by Email. Follow @Chris_Ciaccia
