2 or 4 wires it is probably phone, 8 wires is probably data.

You're talking about the pinout? Because it's an 8 pin plug. It's 568A

How many wires are actually connected in it. (spelling/auto-correct corrected)

I'll have to check but from the brief check behind the wall plate I took it looks kinda like two sets of 4 pins for a total of 8 going to the port.

Other thing to check is color of wires. Data is blue with white stripe and a white with blue stripe. Same for green and orange and brown I think. Phone lines will have all solid color wires, red green black? Yellow? All pins have wires connected? Probably striped wires? That would be data.
