HP quickly confirmed rumors Tuesday through unveiling its first-ever cellular version of the TouchPad. Labeled as the TouchPad 4G, it adds support for HSPA+ 3G and can get cell data either prepaid or on a subscription. The webOS tablet is, in a rarity, also a genuine upgrade on its own: the new version uses a 1.5GHz dual-core Snapdragon instead of the 1.2GHz chip on Wi-Fi only TouchPads.
