AT&T is scrambling to rebrand all its 1,800-strong chain of former-Cingular US shops in advance of iPhone's launch next month.

The company – which acquired Cingular when it bough BellSouth last year – is rebranding the mobile network under the AT&T moniker.

Speaking to Reuters, AT&T spokesman Michael Cole said: "The iPhone is one of the most anticipated handsets ever in the wireless industry, and we want to make sure that every drop of equity from the iPhone accrues to the AT&T brand.

"We want to be as far along as possible with our rebranding in advance of the launch of the iPhone."
