you cant make calls, while on 3g/mobile network, at least, not just yet.
Can u receive calls while on 3g?

Bluetooth is not working ATM. Boostd and I have been discussing a fix.
As far as calls go it's pretty simple, Ill lay it out.
While connected to wifi, sending and receiving calls work just fine.
While not on wifi, if you hava data running, you can not use the phone function.
If you turn data off, phone functions as normal.
HTC was nice enough to build a widget right into the rom so you just hit one button to turn it on or off. So it makes it quite manageable if you want to try the rom.
Text messaging works fine on any configuration.
