I’ve had this Nokia SU-8W bluetooth keyboard below for a few years. It’s really pretty cool and folds up into a very compact little box – great as a note taker for meetings. Of course Apple doesn’t like you using anything but their gear (*grr*) but I can finally rejoice because thanks to a nifty little (jailbroken) app I have my old portable keyboard working with my iphone and ipad.
1. Jailbreak your iphone. I’m using the latest version of ios 4.2 above.
2. Search Cydia for an app called BTstack Keyboard. It costs $5. Install.
3. Open the newly installed keyboard app and connect to your device.

Sadly the SW-U8 keyboards are no more but you can get them on ebay for between $35 and $70.
