I know it seems like the day will never come when your Galaxy Tab gets updated to Gingerbread, but Sprint Galaxy Tab owners will not have to wait much longer! The Sprint Tab is getting its 2.3 update Tuesday July 5th. This update also brings HID Bluetooth to allow more Bluetooth connectivity.
If you do not want to wait for the 2.3 update, then check out XDA Forums for help installing it manually.
