I played around with Tasker back when I first got the Incredible, and it was really neat, but I didn't buy it since the Mobile Data Off setting wasn't working for CDMA phones. It was recently updated and this ability was supposed to be live now, but it still doesn't seem to work for me. I work in a very shielded building so when my phone senses the wifi network I want it to turn the mobile data connection off to prevent signal searching and associated drain. Anyone else have any luck w/ this? It's an awesome app w/ a lot of control, but this not working just leaves me using Timeriffic instead.
