I have a jailbroken and unlocked 3GS running IOS 4.1 with Ipad baseband 6.15. I've tried to pair it with Motorola H500 and Samsung WEP470 headphones but it will not associate. During the process for a short period each device gets detected, but then it disappears and I never get a passcode prompt. Is there any known issue about it, are my BT devices incompatible, or any missing step in my procedure? Phone works fine with T-Mobile, even GPS seems to be close enough to consider it functional. Any suggestions appreciated. My Iphone is the newer generation 3GS.
