Sync contacts to your iPhone

Wrangle your contacts onto your iPhone with Plaxo, and keep them all in sync at work and home. Plaxo will sync your data across platforms like Outlook, Google, Yahoo, Thunderbird, AIM, and Mac’s Address Book. Plaxo will even update your friend’s address book anytime your contact information changes. And this is all included in the free basic service. The premium version includes many other features such as syncing with your LinkedIn network and auto back up of your data.

Note: We know firsthand why Plaxo earned a bad rep for they way it used to send email notifications to your contacts (ahem..spam). Thankfully, they no longer do this so you might want to give them a try. Their syncing technology is top notch.
