I currently have an Iphone 3G with firmware 4.2.1. I have a problem with bluetooth. After some research on the internet, it appears that this firmware version has a bad bluetooth stack.
It should be fixed in a more recent version, but 4.2.1 is the last version for the 3G.
Anyone tried to install a version (4.3.3) for a 3GS on a 3G? Is it possible and will it work?
