Thanks for that.
I've upgraded the radio to 1.13 and the BT to 3900. Now I can call out and receive calls no problem except for one MAJOR pain in the ass...
When the device goes into standby mode, a received call will not wake up the device and reconnect the BT headset in time to answer the call - I have to answer it via the device green button. I've looked through the forum and found that a few people have had this problem. I realise that not going into standby mode burns up the battery more quickly but I'm hoping for a way to get a compromise... i.e. standby for the screen and the processor, but bluetooth and the headset connection still active.
I've yet to upgrade my ROM to 1.31 (from O2 UK/IRL) or 1.40 if I figure out how to rejig the iMate ROM for my XDA. Has anyone had any experience of a ROM upgrade helping (or worsening!) this problem.
Better yet - anyone have a workaround?
Your advice is much appreciated...
