Verizon Wireless, the joint venture  between Verizon Communications and Vodafone since 1999, announced today some record-breaking sales in devices sold in the debut day. Starting yesterday, Verizon Wireless allowed users to pre-order the iPhone ahead of  the official release day and the requests were unexpected. The company refused to disclose the number of unit pre-ordered, yet the sales exceeded performances of similar products such as Motorola Mobility Holding’s Droid and Research Motion’s Storm, both having been marketed thoroughly.

The official launch day for Verizon’s iPhone is February 10^th, available from  Verizon Wireless, Apple stores, Best Buy and  Wal-Mart stores across America. The company encountered no major difficulty in dealing with the pre-orders, but a few minor errors due to increased web traffic on both Verizon Wireless and Apple’s websites during the first hour of availability.

Lately, Verizon has made heavy investments in supporting its network for its customers, the sum going up to $57 million across Delware’s landline communications. “Through our aggressive investment in the latest technology for consumers and businesses, Verizon is helping to position Delaware as a technology leader,” said William R. Allan, president of Verizon Delaware. “From the smallest home to the largest business, Verizon’s networks and technology touch lives, and our substantial investments benefit our customers, employees, suppliers and communities.”

All players in the field try to keep out of trouble with network issues such as those noted with AT&T. The latter found itself in legal trouble when a suit was filed against AT&T this week by a customer bringing evidence in court for AT&T making money by overcharging customers on iPhone data plans.  If this was not enough, AT&T also lost the battle of exclusivity over iPhone to Verizon and the situation is about to get worse.

Currently, AT&T’s revenues do not meet the expectations of Reuters that predicted 504,000 contract customers and the reality indicated around 400,000. Moreover, analysts predicted $2.73 billion revenues, whereas they dropped to $1.09 billion. Yet, Chairman and CEO Randall Stephenson sees 2011 as opening the road to success, given the sound investments made in the last period that will start to show returns.
