Hello, phone numbers (from previous phone Nokia) have been loaded on my BB handset via the SIM card. My contact email and postal addresses are in my Yahoo email a/c which I use as my primary email on my PC. I have just sync'd the Yahoo details to Outlook on my PC via Yahoo Sync. I have manually updated (some) impt email addresses on the handset. Is there a way to sync the details (email addresses and postal addresses) held in Yahoo / or now Outlook on the BB without overwriting the SIM card details and those details manually updated ? Many thanks.......
