Contacts synchronization is always one of the hottest topic in the mobile device. There are basically two ways of doing contacts synchronization, i.e.

  • Offline; meaning you don’t need Internet connection to do synchronization.
  • Online; meaning your contacts are backup to an online server.

Contacts synchronization

Offline

  • Microsoft Outlook. I am pretty sure that many of you have been using PC Suite to synchronize your contacts to Microsoft Outlook. The latest PC Suite even supports synchronization to Windows Vista contacts.
  • Apple’s Mac. Mac users may also be familiar with iSync. Personally I’ve never tried iSync yet because I don’t have Mac. However, I heard that this product is awesome; just like any other Apple’s products.
  • Mozilla Thunderbird. There were some discussions about contacts synchronization to Mozilla Thunderbird. Until today, I haven’t managed to synchronize between S60 devices and Thunderbird. There is a product, called NokSync to synchronize Nokia phones. Unfortunately, it doesn’t work with S60 devices.

Online

Online backup for contacts is getting increasingly more popular these days. There are many companies out there that are providing online backup service. My favorite online backup services are:

Plaxo uses proprietary protocol for synchronization; while the other two, Zyb and Mobilcal, supports SyncML. For those who are not familiar with SyncML, it is a platform independent information synchronization standard from OMA (Open Mobile Alliance).

I am going to discuss online backup in the next postings. So… stay tune…
