Query: NOT BLACKBERRY COMPATIBLE

iGo Stowaway Ultra-Slim Bluetooth Keyboard for Blackberry and other PDA/ HandheldsReceived this as a gift, and spent more than an hour trying to peel off the sticker placed OVER the keyboard. 25% of the keys were covered in unremoveable sticker remnants. Finally removed using toxic goo-gone, but not worth the effort, since the product is NOT (even though it states that it is in the product name) compatible with my newer model blackberry. The product's customer support staff was completely unhelpful, and told me that ALL of the drivers on the CD were out of date and that my newer model blackberry was only compatible with some other random product they offered. DON'T DO IT unless you (a) have an unusually high tolerance for picking stickers off computer keys and (b) don't actually need a keyboard you can use!
