Supertooth Buddy - Bluetooth Issue

Hi,

I'm having issues pairing my iPhone 4 with my bluetooth car handsfree kit - http://www.supertooth.net/EN/buddyspecs.htm.

The story goes as follows...!

I smashed my iPhone 4 by accident on Tuesday - this phone paired correctly with the handfree kit. I received a replacement phone Friday and set this up ready to use with the handsfree kit - however it will not find the Supertooth Buddy regardless of what I do.

I have tried everything. I even turned on the smashed phone to make sure that it would still connect - it did within seconds. I then clicked on 'forget this connection' and cleared the memory and tried to re-find the bluetooth kit - it wouldn't.

Is this due to a recent update on the iPhone software or am I missing something - i'm using OS 4.3.3?

I have tried everything so any help would be appreciated!

Thanks.
