Sprint changed its mind about providing 4G WiMax service on the Blackberry PlayBook tablet, even though it will still sell the wi-fi version.

The reasons Sprint cited to change its decision are that the device hasn't yet won over consumers, and there are too few tablets on the market currently that it will create confusion, according to wSJ.

"It's an interesting concept, it just hasn't caught on with business customers as much as thye would like" said Sprint's business markets group president Paget Alves.

The wi-fi PlayBook version sells for $499.99 in stores and features a 7-inch touchscreen.

With Sprint dropping the PlayBook, the Blackberry tablet no longer has support from a U.S. carrier.
