You may sync your mac with iPhone via iTunes, as always with iPhones, check whether version is compatible with last iOS. Then your iPhone may sync with iCloud. I still have a 12 in PB made in 2004, it works fine with my iPhone, just it is older, the first iPhone on the market, it sill works fine, no need to replace it.
Before testing anything, backyp your data, just in case you make a mistake, always do that.

Actually, you can get email directly on the Powerbook. The "app for that" is an IMAP compliant email client, and Mail in 10.5 qualifies. You just need to enter the settings for iCloud. Apple has supplied the info here http://support.apple.com/kb/HT4864.
