Off subject: The supported carrier Id key is in the bundle but the iPhone reads an nv item to determine which bundle to use, correct? Otherwise changing this key would cause iPhone to look for a different bundle?

Every time I make a change in the bundle I have to increment bundle version?

I looked through carrier.prl which is the only file unreadable but thats not where nv items are at... I know there is a decompiler ida pro but that's probably not it. Can i get a hint: Do I use a hxd on a system file to read the nv item?
