I bought the first iPhone when it was released. It didn’t have stereo bluetooth support, that was on the newer iPhone 3G.
However, except for the network adapter, both were hardware-wise exactly the same.
I found a kext file in my phone, that had disabled the function, as in:
“Bluetooth_stereo = false”
After enabling that, it worked like a charm.
That was the last iPhone I ever bought.
And trying restore a lot, don’t be like me!
