Hi, I'm currently on holiday in Greece and bought myself a Greek prepaid card. Now I want to create a hotspot and share it via Bluetooth, which works fine with my iPad 3 but doesn't if my girlfriend tries to pair her 3GS with my 4. I know that it works via Wifi anyway but since I only have a quite crappy data connection here anyway I wanted to use Bluetooth as I've read that saves battery. I know it's not that important, but I'd like to know why I simply can't pair the two phones. Thanks!
