I'm planning to get S2 sometime next year and I was wondering if oyu have S2 on one computer, could it be unlocked on anothrer computer with the same account?

yp but you cant use both at the same time...only one at a time!

my account is unlocked on my 2 computers!

Unless, you can do it on LAN with 2 people on at the same time.

Alright thanks.
