I finally got the keyboard case for the iphone 4 which basically solves my problem with the annoying keyboard touchscreen. iPhone 4 BT Keyboard Case works as a wireless by attaching it to your iPhone [similar to a cover] simply open your bluetooth and connect the keyboard case to your iphone.
Everything is great about it except that the buttons aren't bold which makes typing less comfortable and the space bar isn't in the middle of the keyboard, however you'll get used to it through time.
I don't know if the Keyboard Case is available in Kuwait but I've received it from my cousin at Dubai Mall.
