As I understand it, the locked bootloader on the RAZR will prevent using custom kernels. I just read this on the android wi-fi tether page: android-wifi-tether "This application requires a "rooted"-device and(probably) a custom-kernel which supports netfilter (iptables)." I have no idea what netfilter (iptables) means. Does this mean that the RAZR will not support wireless tether (except the carriers official version, of course!)? This would be an absolute deal breaker for me and I'll have to cancel my pre-order asap.
