Sorry if this has already been addressed. I did a quick search and didn't find anything.

Just have some really basic questions.

Does the Nokia Lumia 800/900 support WiFi tethering (hotspots) with the phone sourced through either/or Telecom/Vodafone and does the Lumia 800/900 support VPN natively?

If the Lumia range doesn't currently support VPNs natively are there market options that would provide a stable secure PPTP, IPSec connection and/or etc.

If one had a home NAS, how would one using a Nokia Lumia make a secure connection to a VPN Server?

Sister would like to buy a Nokia Lumia 800 and thought I should do some ground work first.

Thank you for any advice.
