Looks like Sprint isn’t ready to abandon their current 4G network yet. Paget Alves, president of business markets at Sprint recently told Forbes that a 4G tablet will arrive in 2011. He wouldn’t let out any details about where or who would make it, but he hinted that they plan to sell tablets running different operating systems. This means it will be from a selection of the PlayBook, a future Android tablet that runs on 4G, the HP Palm webOS tablet and possibly the next iPad? Or something that we’ve never heard of before? Whatever it is, things definitely do sound like they’re getting interesting over at Sprint.
