We have just released our app called All Contacts. Our application is designed to allow you to browse all your contacts in one place. Currently it supports three sources of contacts: internal iOS address book and address books from your Facebook and Gmail accounts (more than one is allowed). More address book providers will be added in next release soon. Key features: - Able to receive and keep your contacts and groups up-to-date from Gmail and Facebook acсounts. - Allows you to add multiple accounts for external address books. - One-click access to your friend's Facebook profile from the contact information screen. - Browse all contacts or all groups together. - Uses OAuth and OAuth 2 protocols for authorization, so your passwords are not stored in your device. More features coming soon! iTunes link (screenshots, etc.): http://itunes.apple.com/app/all-contacts/id504194126?mt=8 Your feedback will be greatly appreciated!
