BTstack Keyboard App Grants Bluetooth Keyboard Access to Jailbroken iPhones, iPod Touch Units
If you’re brave enough to jailbreak your iPhone, there are some upsides to the endeavor.
A small application called BTstack Keyboard by Matthias Ringwald allows jailbroken iPhone 3G and 3GS users to use a bluetooth keyboard for text entry with their iPhone.The app should work with most any bluetooth keyboard available.
The keyboard is available for $5 on Cydia Store and requires an iPhone 3G or 3GS or iPod touch with Bluetooth support. It’s unknown as to whether it works with the original iPhone 2G.
