Microsoft My Phone Beta is a mobile service that stores your phone’s data to a password protected web site. It enables you to automatically backup and restore your phones information including Contacts, Calendar, Tasks, Text Messages, Photos, Videos, Music and even the contents of your storage card.
I just came across PIM Backup for Windows Mobile 5.x & 6.x and Windows Mobile 2003 SE which can backup and restore personal information stored on windows mobile based pocket devices like contacts, appointments, tasks, messages, calls etc. PIM Backup is completely independent of the version of Windows Mobile or the hardware or even the language on the device.
This is a nice tip to keep track of the Birthdays and Anniversaries of people you personally know so you never miss to wish them on their special days. Outlook contacts can store Birthday and Anniversary information as personal information. When you add the Birthday or Anniversary of a person, it will automatically add an All day event into your calendar showing the event as an all day event by displaying on the top of the days calendar entry and marks it as “Free”. What more, as always you can set reminders on the entry as with any other Calendar entry.
