X230 MC7710 drivers from Lenovo?

[mars83]

Hello!
I bought my X230 last fall and I love it. It had pretty basic options (I bought it used - nearly brand new). I added to it backlit keyboard, MC7710, palmrest + fingerprint reader. Now I was wondering few things:
1) Can I add 3rd antenna for MC7710 somewhere in the palmrest area? I'm thinking about connecting GPS chip
2) Can I use Lenovo's drivers for Gobi4000? If yes, how? Technically 7710 is like 7700/7750.
3) Is there a NATVIE way to send text from Windows 8.1? I have to use Sierra's Skylight which is uncomfortable for text
