Did you do all the wipes before installing the rom? When I suggested this I thought it might have the option like on there wifi Moray rom to turn off the update. If you made a backup you can restore to get wifi back, also you might try the ICS EOS 1.0.0 rom. It's the most current up to date rom, I'm running it on the wifi version and am not getting any OTA notifications. On this rom you will need to download and flash the rom and the gapps package with no reboots between the two. There's a wifi, 3G and a 4G rom.
