AT&T

With the exclusive iPhone deal between AT&T and Apple ending this summer, Verizon is reportedly in negotiations with Apple to offer a CDMA version of the device on its network this year. Maynard Um from UBS Investment Research wrote a note to investors that stated, "We believe a CDMA-iPhone is also in the works, though we believe Verizon Wireless and Apple may currently be apart on pricing."

Um's research points to a new iPhone release this summer, including a CDMA network compatible iPhone for Verizon or other CDMA carriers in Japan and China. Ongoing negotiations between Verizon and Apple have been rumored to be happening frequently in recent months. The release of a Qualcomm hybrid chipset that supports multiple wireless network technologies has also added to speculation.

Yet another snafu in AT&T Wireless' public relations efforts has surfaced. Customers interested in purchasing an iPhone via the company's website in the New York area are finding that the product isn't listed.

Zip codes in New York City, northern New Jersey and Westchester County have had the iPhone removed as an option for online purchase. Representatives of AT&T have simply stated that distribution and promotion channels are periodically changed.

The exclusive US carrier for Apple's iPhone has released an application devoted to reporting problems with their network. AT&T will even send a free SMS to confirm receipt of your feedback.

The exact latitude and longitude of the occurrence along with specifics of the problem are sent directly from the application. The main menu offers options including Dropped Call, Failed Call, No Coverage, Data Failure and Poor Voice Quality.

This may come as no surprise to iPhone owners: AT&T ranks last out of the four major service carriers when it comes to customer satisfaction. Consumer Reports surveyed 50,000 wireless subscribers in 26 cities for the annual report.

Speculation has been rampant over a Verizon Wireless iPhone, however a simpler path for Apple to expand its iPhone market would be to offer the device to T-Mobile. Doug Reid, an analyst at Thomas Weisel, sees this move as a logical step.

Apple already offers the iPhone through Germany's T-Mobile unit (T-Mobile is owned by Deutsche Telekom). The carrier has compatible wireless technology to AT&T and wouldn't require any hardware changes to the iPhone, unlike any move to Verizon Wireless.
