I'm having problem with starting AvantGo on my 3650. Each time it starts, it takes horribly long although I have more than 2MB free memory available on the phone (not MMC). When I try to sync, the app will hang, and then close with an error message App. Closed. I had to restart the phone after that.
So now I not only have to recharge my phone daily, I have to restart it daily too if I ever want to use AvantGo. 😞
