Plug your phone into the computer and make sure it is in debugging mode. Open command prompt (I assume that you know how to use CP and adb shell but if you don't then I can break down the steps). Navigate to your android/tools folder and type this:

adb shell
mount -o remount,rw -t yaffs2 /dev/block/mtdblock4 /system
cd /system/etc/security
mv otacerts.zip otacerts.zip.bak

OTA updates are blocked!
