Question about data connection.

[LukeB777]

This may have been answered already but couldnt find it in a search. I run off the alltel network and was wondering if I left my data connection active will it drain battery life substantially even if I dont use any programs that use a data connection (arrows are grey most of the time.) Just wondering cuz I have a program that has scheduled updates and wanted to just leave it running. But if its a big drain on my battery I will just shut it off everytime.

Thanks for the help and what a great site this is!
