Looks like some detail has been leaked to the net wave on just what the Big Blue is expecting to offer customers in Q4 and in time for the festive season push, which includes BlackBerry, Android and Windows Phone 7.

According to Darren Murph over at Engadget, AT&T will be offering the BlackBerry faithful 3 colour options on the BlackBerry Torch 9800 which will be a white version, a red/black version and an olive version of the smartphone which is expected to hit mid November.

Then there is one of AT&T’s first Windows Phone 7 devices, the Samsung Cetus and one that’s not been heard of before, the Samsung Focus and the HTC Surround, and apparently another 3 Windows Phone 7 devices all before the festive season.

Last but not least, AT&T will deliver the Samsung Galaxy Tab Android 2.2 tablet along with 3 new Android based devices which will apparently ship “prior to December.” More as and when we hear.
