Hello, i have a Thinkpad T60 that i am looking to get set up with WWAN. Their are two 3g antennas, a sim slot, and space to install the pcie device. I like ubuntu very much so far but sometimes I know hardware compatibility can cause problems. Has anyone had success installing an internal 3g device like this before? (USA service plans if that matters) If so, which would you recommend me to buy? thanks.
