I have the same problem on .75... I don't think it was happening before I upgraded but I can't be sure. Did anyone else notice it happening on the previous version?
Yup...known issue. I have the same problem and I only use .75. I am new to BB and am not messing with a 'leaked' version when I have no problems other than this one and the occassional dropping of the bluetooth connection.
I had a similar problem - the Bluetooth would be "on" but the Verizon network would not turn on consistently. (Somedays yes, somedays no.)
I called Verizon, thinking it was some setting that I had inadvertently changed, and they said it was a known issue that was being corrected in a future firmware upgrade. (Their words, not mine.)
