Apple Inc. shares reached an all-time high Tuesday after a newspaper report said the iPhone could find a new U.S. sales outlet through Verizon Wireless. Since its 2007 launch, the iPhone has been available in the U.S. only to subscribers of AT&T, which uses a cellular network technology called GSM.

The Wall Street Journal reported late Monday that Apple plans to release an iPhone this year that would work on CDMA networks -- a technology used by Verizon Wireless and Sprint Nextel in the U.S., as well as some carriers overseas.

Apple, AT&T and Verizon declined to comment on the matter.

AT&T has thrived as the sole U.S. iPhone carrier despite paying a massive subsidy to Apple for the exclusive rights to offer the phone. At the end of 2009, it was the second-largest wireless carrier behind Verizon Wireless in terms of subscribers.

But the iPhone's popularity has taxed AT&T's networks in cities such as New York and San Francisco, leaving the carrier vulnerable to an aggressive ad campaign from Verizon. AT&T said in January it would spend an additional $2 billion to improve its network this year.

Apple and AT&T have not said when their exclusive deal will end, though some analysts have predicted Apple will begin offering the iPhone through multiple U.S. carriers sometime after it unveils the next-generation iPhone this summer.

Shares of Verizon Communications, which owns a majority of Verizon Wireless, rose 2.6 percent Tuesday, while the stock of its partner, Vodafone Group PLC, edged up 0.8 percent. AT&T dropped 2.1 percent.

The number of people using smartphones to surf the internet is up by 13 %, according to the latest figures released by AdMob. The research group's monthly Mobile Metrics report found that 48 per cent of mobile internet traffic was generated by smartphone owners, which is up from 35 per cent in the same period during 2009.

The number of people using Android smartphones and the iPhone is also on the rise, as Apple's mobile managed to account for 50 per cent of mobile internet use in February. Google's platform made the biggest gains, jumping from two per cent in February 2009 to 24 per cent last month. Nokia's Symbian platform is shown to be the biggest loser, with its previous traffic figures of 48 per cent falling to just 18 per cent.

Admob advises that these figures do not provide an accurate representation of smartphone market share, however analysts believe that the large app stores which are present on the iPhone and Android platforms are driving the change in mobile data usage.
