Apple is to hold an event at the beginning of the upcoming year, possibly before Valentine’s Day on February 14, 2011, and the aim of the event is to present the new CMDA version of the iPhone compatible with U.S. carrier Verizon’s network.

This might present a huge problem for AT&T, the current exclusive carrier of the iPhone in the country. Being an exclusive carrier for the magic device meant huge sales and bad press – a recent reader poll from Consumer Reports ranked AT&T as the worst carrier in the U.S.

“Verizon enjoys a reputation for reliability,” author Peter Burrows wrote. “AT&T is notorious for dropping calls, especially in densely populated places like New York and San Francisco where iPhones are most common and cell towers get loaded.”

So it is time for Verizon to carry the iPhone and Apple will hold its own “splashy products introduction to announce the new version of the iPhone.”

Although some speculated that the new iPhone would be introduced at the Consumer Electronics Show starting in early January, but that is not the Apple way. “Apple’s introduction of an iPhone for use on Verizon’s network will come sometime after the Consumer Electronics Show in Las Vegas in early January, according to a person familiar with Apple’s plans who is not authorized to discuss them publicly,” Burrows wrote.

This is long-awaited move from Apple, and one that will cause concern for the people at AT&T. However, the report suggests that Verizon is also likely to have weaknesses, so those of you who plan to change carriers at the launch of the new iPhone, just be prepared.
