BlackBerry Curve 8330

I just set my Curve last night and am having problems sending emails from my phone intermittently. Another problem is that when I receive emails they only show up in my messages icon and not in my email icon. The red asterisk shows up on the messages icon but not on my email icon. I had a Pearl and never had problems. I called tech support and they had me check the settings which were correct and their solution was to try a hard reset. Any other suggestions? I just received the Curve Saturday as a replacement to my Pearl.

Thanks!
