If I purchased a G2X to replace my Nexus One will I have to additionally pay for Hotspot/Tethering? I was checking out the G2X on Amazon and under services it lists Tethering and Hotspot at $15 and $10 respectively. Does this apply to Android phones using 2.2 and higher (both features built in and I was never charged for Hotspot mode on my Nexus One) or that just showing since other devices might require a fee?
