SMS and E-mails wake phone

[djg08642]

Sorry to start a new thread for this but I did search pdaphonehome, xda, and here and didn't find anything specific.

I had a Samsung i760 prior to having this phone and it didn't wake up when I received text messages or e-mails which I liked in case I couldn't answer the phone right away and my pocket would end up replying/calling people.

Anyway, is there a regtweak to prevent the phone from powering on for notifications other than phone calls?

Thanks.
