You will need a Jailbroken iPhone to be able to this.
My iPhone has OS 3.1.2 and I used Blackra1n to Jailbreak. Here is the post I did when I Blackra1ned my iPhone.
The BTstack iPhone Bluetooth Keyboard App can be purchased on Cydia for $5.00.
I installed BTstack and when to Best Buy on Monday to give BTstack a run. It had a nice wow-factor but I just couldn’t see lugging around a BT Keyboard. I will keep my eyes open for a cheap BT keyboard but I can’t see me spending $60 for the Apple BT Keyboard.
