Locked in to Vodafone options from iphone?

Hi all, new to site hope you can help.
Just changed to Apple Mac from PC want to change to iphone but locked in to Vodafone for another 18 months!!!!....
Can you recommend another phone that will link well to the Mac??

Just google the model for its compatibility with iSync. I know that Nokia has started creating their Mac software for multi media synchronization with itunes and iphoto (but still in very early beta) and most of the symbian running handsets are iSync compatible (for ical and address book) & if not you can easily find third party plugins for iSync easily which makes your phone compatible with isync.

Thanks for that!!!.... I think I'll wait till sept and get a iphone
