Apple Inc plans to announce a fourth-generation version of its iPad (4G iPad) in the first week of March, a Wall Street Journal report said, citing a person briefed on the matter.

Visitors check out the new Apple iPads at an Apple retail store in Madrid May 28, 2010. The iPad officially went on sale on Friday in Spain.

Verizon Communications Inc and AT&T Inc will sell the new iPad version that will run on the companies' 4G network, the paper reported, citing people familiar with the matter.

AT&T and Verizon Wireless are the only two U.S. carriers that currently sell the iPad, and are also the only two that offer the fast, next-generation wireless technology known as LTE, the paper said.

Apple was unavailable for comment outside regular business hours.
