AT&T Inc plans to launch 20 phones with high-speed Web surfing this year including a phone from Motorola Inc.
AT&T has been the exclusive U.S. provider for the Apple Inc iPhone since its 2007 launch. It is looking to expand its smartphone lineup as it is expected to lose iPhone exclusivity this year as Verizon Wireless is expected to start selling the popular cellphone.
AT&T's President and head of mobility Ralph de la Vega also said on Wednesday that AT&T would speed up its plan for upgrading its network for higher speeds with a launch around the middle of 2011.
De la Vega said at an event ahead of the Consumer Electronics show that his company expects to have its national high-speed upgrade largely complete by the end of 2011.
Motorola said its Atrix 4G phone will attach to a laptop so consumers can take advantage of the bigger screen for Web browsing or using videos.
AT&T also said it plans to sell a high-speed phone from HTC Corp called Inspire 4G.
