Just go into your mobage settings and log out, then you can log in from any other device.

I recently tried logging in to my account simultaneously with Bluestacks and my phone, and the new login kicks the old one out with a 'game is being updated' message. Good to know.

But as for the account, it is all stored server side, there is no reason you cant log off your account on Android and then log in using an iOS device, or vice versa. You can even test it before logging out, you can store the account information on multiple devices no problem, they just can't both be on at the same time. So copy your acocunt information to the new device before doing anything to the old one. It should work.
