I've only been rooted for a couple days so haven't had a lot of time to play with it. I have Velocity 1.1 and I'm trying to update my Yahoo Mail app. I keep getting update unsuccessful with installation error "package file is invalid." I got the same problem yesterday trying to download the FB app but after trying it over and over it finally worked. Is there something wrong or a setting I need to change? Am I the only one having this problem?
