Apple says it's looking into an issue that requires some iPad 2 owners with built-in Verizon 3G to reboot their devices to re-enable 3G after turning it off.

In a statement by an Apple representative released to All Things Digital today, the company said it is aware that some iPad 2 owners with the Verizon 3G model are having connectivity issues and is investigating it. The number of those affected is "small," the company said.

Complaints began mounting on an Apple Support Discussions board in the days following the release of the iPad 2 with some users finding that the software switch to turn the 3G antenna on and off was not reactivating without first powering down the unit.

The Verizon version of the iPad 2 is the first iPad to ship with CDMA service. Verizon's 3G service is also offered on the CDMA version of the iPhone 4, which went on sale earlier this year. Both devices use the same software mechanism to turn the 3G modem on and off.
