I removed ad support from my app. This is due to the cancellation of my admob account. I do not know why, but my account was flagged for illegal activity and banned. I find it fairly humorous since In the 6 months of being active my account managed to make about 40 dollars before being banned. I was required to make 50 before I was allowed to withdraw any of it. I would have made more money begging on the street but google admob wouldn't even let me have that.
So anyway, I took the ads out of my app which is still available on the Android market and is now completely free.
