Reported on 9to5mac.com, the released beta of iOS 5.1 with new firmware for the iPad. Likely the new iPads launching in March – having appeared months ago, it’s possibe this iPad 2,4 could be the Sprint version that Apple recently completed work on – but only if it has WiMAX. A 3G-only Sprint iPad would be the same hardware as the Verizon iPad. Other options include an iPad for China’s TD-LTE, an early LTE model or a dual-mode device like the current iPhone 4S. The rumored March iPad 3 launch quickly approaching so there will be more information to come.
