Apple has just updated its online store with a shipping date for the 3G-equipped variants of its iPad. As you can see, all varieties of the hallowed Apple tablet should be out and about by May 7th -- meaning that some deliveries could sneak out even earlier -- and you can expect AT&T will be ready and waiting for you to activate that $30 a month unlimited data plan. Just for the European record, that means the iPad will be out in full force for American consumers three days ahead of the announcement of specific international availability. Ah well, at least that gives the UK and others hope that they might see the 3G and WiFi-only slates coming out at the same time, which should be somewhere around the end of May.
