My Tour- which I love, despite this- runs quite slowly sometimes. It lags, is what I'm saying. I'll press a button to open something up and it'll take a good second and a half to load it, and that's if it's something small, like the menu screen. But when I try to open AppWorld? A good ten minutes. It gets annoying. So will Bell Canada give me a new one for it?
It could also be your carrier. Talk to your reps with your carrier and let them know whats going on. Also make sure you are running the newest OS. Good luck.
