Sorry, I have no idea, that's way beyond what I know.I'm not talking about the wifi radio. I'm talking about the cellular radio. When there is no cell tower nearby, the phone will hunt for a new tower. I'm wondering if there is anything built into the rom that controls how aggressive that tower hunting is. With the stock roms, turning on airplane mode does not kill the tower hunting (from what I observed during battery tests), but users of AOSP's CM7 report that their phone can stay on for weeks at a time with airplane mode enabled which leads me to believe that their rom is truly disabling the radio while the stock roms are not.
Ah you know what I was the one that add it back on the phone by flashing the stock sounds you had in the second post, sorry I didn't clarify that on my post. I just wanted some of the alarm ringtones I had gotten use to and instead got things back that I didn't want also
So go into the zip, delete what you want to not put back, copy it to your sdcard, go into recovery, disable signature check, flash the file.
Or use the raw files on your Sdcard, it will let you use them from there.
