Hi everyone,
I have an iPhone 3G jailbroken with 2.2 FW. I don't want to update the FW to 2.2.1 right now. When I open iTunes with my phone plugged in, it says there is an update for the carrier settings available. Does anyone know what it is, if it's necessary and if it is safe to update this on a jailbroken phone?

Thanks

this has been discussed previously. a few jailbroken people (myself included) have done this update without any issues. I don't think anyone is sure of exactly what it is for, but this page describes their general purpose.

I did the carrier settings update in iTunes http://support.apple.com/kb/HT1970 a while back but I'm still on 2.2 FW. Will the carrier settings update currently prevent unlocking?
