AOL introduced on Thursday a new sync application, AOL Sync, that will sync your AOL address book and calendar with Outlook and mobile phones. AOL has partnered with Funambol to deliver this bidirectional, over-the-air sync client. Funambol, for those who don’t know, is a popular open source synchronization solution that uses SyncML to push PIM data to mobile devices and desktop applications. Basically, it’s the poor man’s Exchange / BES. The AOL sync client supports Outlook, Outlook Express and both Windows Mobile phones and BlackBerry handsets. You will need to install the sync client on your phone or desktop, configure it to sync with the AOL servers and voila, automatic OTA bidirectional syncing. Though it is not listed as being a supported device, there is a Funambol sync client for the iPhone and for Thunderbird / Sunbird (experimental) as well. If you can get the AOL settings, it may be worth a try to see if those other platforms work, too. If you are an AOL user, give it a try and let us know if the new client lives up to AOL’s claims.
