Thumbdive is the perfect iPhone application for those who wish to always be in contact with their friends or family. It allows you to have long conversations with people in your SharingPool and share content from your favorite social networking websites (if you wanted, you could share content from all of them!), all from your iPhone.

First, you should install the Thumbdive application on your iPhone.

Next, add your account information for your favorite social networks.

Thumbdive will automatically download the latest updates from these social networks.

For example, if you added your Facebook account to Thumbdive, it would download your latest status updates and share them with anyone in your SharingPool.

Also add RSS feeds of your information, such as the RSS feed from a WordPress blog. Then, build your SharingPool.

Your SharingPool is your list of friends that you wish your latest updates to appear for. You also will be able to view their latest updates. Finally, keep in contact with your friends. You can use Thumbdive to talk to your friends. Someone in your SharingPool can join in on your conversations with other friends, based on your privacy settings.

This is similar to a forum, where anyone can post a reply to a topic that has been created, with a touch of instant messaging. Having quick chats with people that are in your timezone and using Thumbdive at the same time as you, or have long distance chats that continue for weeks or years.

Thumbdive includes an in-depth privacy system, allowing you to select just who can view your status updates and join what conversations. With a little setup, you can stay in contact with everyone that you want to be in contact with, without letting other people read in on your conversations.

The Thumbdive App is in beta right now. It will be released to the general public soon, but until then membership is on an invite-only basis. You can apply for an invitation now.
