I have this problem with my i760, this morning I turned on the bluetooth used it for sometime then turned it off, but for some reason the blue LED keeps blinking, I did everything to stop it like, I tried removing the battery and putting it back in again, I tried numerous soft resets but still the blue LED flashes and my phone dims, it doesn't even turn off. btw I checked all the power settings and they are all checked to turn off the pda in 1 min and stuff.
any suggestions would be much appreciated, by the way I have been using spb on my device for a month now.
