Ok so I had an old nano and then I upgraded to a touch and everything worked out fine. But when I go on itunes it says my account is authorized with 2 devices. I already sold the old nano and I'm gonna be upgrading to the new ipod touch 4th gen with camera!!

So my question is is it okay that my account is still set up for 2 devices or is there anyway I could change it like delete my old device and just have it run on my current touch?!?!?!
