I use my phone to upload zip files to clients and these take about 20-30minutes to upload. I have a Sprint Epic 4G. When I'm on 3G (when 4G's not available) the uploads get interrupted when a call comes in.

I need an app that will block and send straight to voicemail all calls when I'm tethering. It can be manual - when I start tethering, I can turn on the app. When I'm done, I'll just remember to turn off the app.

Anything like this out there? Most of the call blockers are more call *filters*. I just want this to block anything that can interrupt my 3G data connection.
