Im wondering if everyone is using the Hero with ATK. I was using the app. until I realized I was not receiving emails. When I called Sprint they said I should remove the app and let the OS control the apps. Since I removed the app., I am getting all my email notifications. With out ATK. My phone is extremely lagy or bugy. It's not a major problem but I do notice the difference in the phone. I guess my question is " Should we be using ATK or not?" I would like to hear everyones thoughts on this. Im just trying to get the best use out of the phone.
