Hi, I've had a problem with my 3GS since updating to iOS5. Every time I receive an SMS/iMessage message the chime ringtone repeatedly plays. The end result is some thing which sounds like "tri-tri-tri-tri-tri-tring-tring-tring" as if it is playing the sound again and again. So far I have tried to restore from a backup, restore as new and changed the ringtone but none of these solutions solved the problem. This error has only come about since updating to the newest version of iOS. On a similar, possibly unrelated note, the vibration in the phone has developed a problem where it sounds as if the vibration motor is failing. The phone vibrates as normal but occasionally sounds like you'd image an electric shock to sound, it cracks and crackles. This has developed separate from the above problem and I don't suspect one has brought on another. If any one is aware of a fix or has the same problem, please post. Thanks.
