Is anyone else having issues with initializing bluetooth on the iPhone 4? I power down my phone every night while charging, and when I get try to initialize bluetooth it gets hung up while trying to go on (see screen shot). It'll finally go on after 15-20 minutes. I can reset the network settings, but this a hassle and I never had a problem on the 3GS. Either I have a defective handset, or others don't use bluetooth as much and are not encountering this problem. Thoughts anyone?
