    The other day I upgraded to iOS 5.1 on my iPhone 4S. I later found that I lost functionality on my iHome iPhone dock/alarm clock and the next day I lost the ability to control my phone via bluetooth in my car--functions that I had prior to upgrading i.e. play/pause, track search, etc. It like my phone regressed to iOS 2. Anyone else have these issues or know of any fixes?

    I lost bluetooth temporarily on my Chrysler after the upgrade. Just had to go back in and re-"pair" the devices.

    Bluetooth Inop

    I too updated to 5.1 when released last week. Now my Iphone 4 can pair with any device but cannot use in phone calls. I have no Audio Sources button when on a call. The problem is that you cant go back...It's a Verizon phone.

    A friend at work has an iPhone 4S with 5.1 and has no issues, works fine.

    HELP anyone?
