I have Mail 4.2 since I upgraded to an MPB with Snow Leopard.

My old iBook G4 has an older version of Mail (can't recall which) and my wife would like to use the iBook for her own e-mailing.

Can I put Mail 4.2 on the iBook and if so how? (It's possible to send and receive Gmail from Mail 4.2 and that's why I'm wondering if I can put 4.2 onto the iBook.)

Comments appreciated ...
