Delete a contact (HTC EVO) This app does the job. It sync's existing and new contacts just fine. I does nothing with contacts that are deleted on either the phone or Thunderbird on the pc. Seems to me it would be a great app if it could remove the contact that has been deleted from the other source.Thank you for your hard work
★★★★★
works properly once everything is configured properly on the PC side
★★☆☆☆
Doesn't work What can I say,with Thunderbird at version 12?
★★☆☆☆
Sync successful, so where are my contacts? Documentation leaves a lot to be desired, however I (supposedly) successfully synced my address book to my tablet... or did I? Just where are my addresses exactly? I go to type an e-mail - nada, none of the addresses in my PC Thunderbird appear in my email app. Where are they, how do I access them?
★★☆☆☆
Doesn't work anymore! I too recently had toupgrade Thunderbird. And now the sync process hangs!
★★☆☆☆
App is focused on developers personal need rather than the market. Found MyPhoneExplorer much better for this space. So uninstalling this App
