Exclamation [Q] How to create a VPN, a Hotspot, sync Android Calendar dates with FB birthdays?

Hy i'm relatively new in the Android market and i have a few questions. I've asked on Android General Help but i've got answer just for one.
So i thought maybe it would better to put them in the Q&A General Help section dedicated to my phone's model.
Here they are: - How do I set a VPN on Galaxy GT S5660 Gio?
- What are the necessary settings to create a hotspot on Gio?
- Is it possible to/is there an app that could automatically sync Google Android Calendar dates with my Facebook friends birthday dates?
So that i can get an alert when a friends birthday is coming, without checking the mail every time for this.

Thank you all in advance, to those who will answer me.
