    Help please!

    I've had my 3GS from new one year now with no problems.
    Since two weeks ago the phone will ring, I'll only get a
    single ring, maybe 10 times a day at random times. When I get the single
    ring the display doesn't illuminate and flash as when I have an incoming call, the screen is blank. The phone is otherwise OK.

    Now, this is driving me mad. I've pressed the home and on/off button together but this has made no difference. I've checked the alarms and timers and there is nothing shown.

    Any idea how I can stop these intermittent rings? TIA.

    Thanks dhlizard. I'm not brilliant with this technology- a generational thing! Will I loose my phone lists etc. If I do what you suggest?
    Many thanks
