These instructions are of OS X. I used Snow Leopard, I don't know if Leopard ships with bspatch or not, but if it does then you should be good. Also, make sure you have MobileTerminal installed on your phone. First get this file and put CommCenter.patch on your Desktop: 3G S: http://iphwn.org/CommCenter_3gs_312.zip 3G: http://iphwn.org/CommCenter_3g_312.zip Copy /System/Library/PrivateFrameworks/CoreTelephony.framework/Support/CommCenter to your Desktop also. Open the Terminal and: cd Desktop bspatch CommCenter CommCenter-hacked CommCenter.patch Now go ahead and delete CommCenter now from your Desktop and rename CommCenter-hacked to just CommCenter. Rename CommCenter on your iPhone to CommCenter.backup in case something bad happens, so you have a backup. Copy the new CommCenter to your iPhone. SSH into your iPhone or use MobileTerminal as root and chmod +x the new CommCenter so that it's executable. Restart your phone. Hit this link from Safari on your iPhone http://m.peacefulinsanity.com/Tether.mobileconfig Or just wait a few hours or til tomorrow when this is packaged properly and available through cydia.
