The anticipated iPhone 5, which is expected to debut next month for the three biggest carriers in U.S., will see T-Mobile bowing out of the competition at first.

T-Mobile USA's marketing chief, Cole Brodman, said the company had expressed its desire to Apple to carry the iPhone, and is reportedly waiting for a response.

Brodman, onstage at the GigaOm Mobilize event, said the new iPhone will not be available for T-Mobile customers in October. He had told company employees the same thing at a meeting last week.

Verizon Wireless and AT&T Mobility are currently the only U.S. carriers to sell the iPhone. Sprint, however, would be the only U.S. carrier offering an iPhone with an uncapped data subscription.

According to a Wall Street Journal report, Sprint will begin selling iPhones with unlimited data plans in October. The next iPhone is rumored to debut on Oct. 4.

T-Mobile also currently sells unlimited plans, and smartphones account for three-quarters of devices sold by T-Mobile. Ninety per cent of those run Google's Android, competing with Apple’s iOS.

T-Mobile introduced Samsung's Galaxy S2 and HTC's Amaze 4G Monday and said that the smartphones will be arriving very soon, according to a CNN report.
