Way to schedule Data Connection on/off

[xion69]

I currently don’t have EVDO in my market so I use the 3G network to activesync to my exchange server. As some of you know if your phone is using 3G data you cannot receive call, as data is priority over voice. I have activesync scheduled to sync ever 30mins but it seems to sync more often thus blocking my voice calls.

So I am looking for a program to allow the data connection to be scheduled to be on for a period of time.

Anyone else having this problem? or have a different solution?

Thanks

BTW Sprint SUCKS!!!
