My iPhone 4 came with iOS 4.2.1 - however, this does not run properly with my car's built in bluetooth handsfree system - it won't allow me to pick up voicemail messages.

The Vodafone store that I bought it from have identified that it is the software, as the store demo iPhone is running with iOS 4.0.2 - and this works perfectly with the car.

Can anyone please tell me, how can I get the software corrected, or a previous version downloaded so that I can gain full functionality of the phone?

Many Thanks.
