Can the same account be used on 2 iDevices?

[Necrocat219]

Erm the case is that I`m on holiday right now and I foolishly dived into a pool with my ipod in my pocket. I shoved it into a ricejar when I got home and have yet to see if it will switch on ^^;

My question is could I use another iDevice registered to another account to play on my account? And also if I were to replace it and register it to the same Apple account, could I recover the account and my purchases?

Thank you very much for your time ^__^
