blinking green led

[samjoandco]

isn't blinking green better for a deep sleep instead of constant green?
We could save some battery that way.

Secondly, is there anyway we can find out what is preventing the phone from going into deep sleep? It works most of the time but some times, it just does not sleep even if GPS, APN is turned off and all applications are killed from task killer. I also have configured task killer to run in background.
