Not spending much time on here at the moment as the car is taking a backseat while I try and work out my relationship with my girlfriend
Installed ios 4.1 Gold Master on my old 3GS phone and sync'd with my B Skoda bluetooth (with red dot display)
Now syncs perfectly, phonebook and received and dialled numbers all come up perfectly on the display rather than the garbage on the previous ios 4.xx firmware
4.1 should be out this week from Apple
Can't test with my iPhone 4 as if I upgrade to 4.1 I'll lose my jailbreak
