[Q] Before I activate VZN GN2? OTA, Teather, Exchange topic

Hi all,

I still have unlimited data and I'd like to make the most of it, so I'm hoping to find out if/how about a few things before I activate my VZN GN2

* Can I block ota update to prevent new limitations?

* Can I sync with MS Exchange server without buying the corporate data?

* Tethering options?... I'd love to drop my cable ISP.

I'd really love to avoid rooting if I possible, so I'm asking for stock options and apps. If I need to root just say so. I can dig around for mods myself... don't want to waste anyone's time. (Off the shelf solutions may be helpful to other noobs)

Thanks for the good work
