I have had the N810 for over a year and recently realized that I have been 'underutilizing' its potentials (I apologize). It has not gotten much use other than in the bedroom or bathroom to quickly browse news or check emails. Of late, I have been reading up on what this device can do and have been amazed at what I found out. (Really, recommend the Internet Tablet School for anyone!)

Anyway, here is what I need help with (I live in US):
1. Is it possible to use the data service of my personal Sprint phone (Samsung Moment) or my work phone (BB Storm on Verizon) for internet services on the N810?
2. Is there an app to make calls with Google Voice number on the N810 without using a phone?
3. Is there a way to use the built-in camera for cam chat with a yahoo, msn, aim, or skype account?
4. Is there an app that can be used for yahoo or hotmail emails apart from using the browser? Something that will be set up to automatically check emails?

I apologize if these have been addressed elsewhere. Do direct me to them, if so. Thanks.
