Apple has announced plans to launch 3G models of the iPad 2 in China, which will join existing Wi-Fi options. The new hardware will go on sale Wednesday, made available through Apple's online and retail stores as well as authorized resellers. Prices have yet to be made public though, and Apple's only Chinese carrier partner -- China Unicom -- has yet to acknowledge the rollout. Unicom is in fact the only carrier in the country which can make use of the HSPA 3G supported by the iPad 2.
