Existing local PIM data can be preserved when synchronizing an iPhone with OS 3.0
Posted by - NA - on 27 July 2009 10:09 AM
If your iPhone/iPod touch/iPad had local contact and calendar data on it prior to creating an account for synchronization with NotifyLink, Contact and Calendar synchronization will default to OFF.  
You can turn synchronization on and with iPhone OS 3.0 or later, you have the option to retain the local data. 
With OS 2.0 through 2.2.1 (iPhone and iPod only), you must leave Contact and Calendar synchronization OFF in order to retain local data.

For iPhone Version 3.0 or later
  • If you want to synchronize PIM items (contacts and calendar events) from the server, but keep existing (local) items on the device, turn Contacts and/or Calendars ON and tap Keep On My iPhone (iPad/iPod).
  • If you want to synchronize PIM items, but prefer that existing (local) items be removed from the device, turn Contacts and/or Calendars ON and tap Delete.
For iPhone OS version 2.0 through 2.2.1
  • If you prefer that existing PIM (contacts and calendar events) be removed and replaced with PIM data from the server, turn Contacts and Calendars ON during registration and tap Save. At the warning prompt, tap Sync.
  • If you wish to preserve the existing PIM data, leave Contacts and Calendar OFF and tap Save.

You can change the Mail/Contacts/Calendars synchronization setting at any time.  From the Home screen, tap Settings > Mail, Contacts, Calendars.  Then tap your account.
