Telecom giant AT&T is reported to have launched a new offer for its customers under the name of "most valuable customers" free 3G MicroCells.

MicroCell is a device that aims at increasing AT&T cellular reception in areas where connection is weak, the sections normally known as "dead zones". The device basically works by tapping itself into the user’s broadband connection placed at home.

Rumors are rife that such an offer initiated by the company is a strategy aimed to keep its customers in the web, as many of them were reported to be on the verge of finishing their contracts. Moreover, many of them were iPhone owners.

The customers were made aware of the new offer and its initiation on their numbers by delivering notices on their mails posting that they qualified for the free MicroCells.

The quality of the call has been witnessed as the major complaint filed by iPhone users in hotspots such as New York City and San Francisco, and the 3G MicroCell aims to partially deal with the problem by lowering the call load from trafficked cell sites.

AT&T has been dismissing the speculations that its iPhone exclusivity may be on the verge of subduing soon, as it attempted to raise up the eligibility for the iPhone 4. This was done in a bid to cover up everyone who would have selected in 2010.
