I currently have the 7130E, and use it as my phone and its also connected the Enterprise Server at my employer, allowing me to receive work emails. If I upgrade to the Curve, do I have to go through my company's Tech Support again in order to have my emails delivered? Or does it work the way upgrading a cell phone always does, where you simply swap out the card? I appreciate your help, I'm trying to avoid company Tech Support if I can.
