What's the difference between the Sidekick ID, Sidekick 3, and Sidekick LX?

My Sidekick ID phone was stolen, so I wanted to replace it with either a Sidekick 3 or a Sidekick LX.

I wanted to make sure the keypad on the Sidekick 3 is the same as the Sidekick ID because I love the keypad it's easy to write on.  Also, I wanted to know if you can use the 3 or the LX the same way you would use an Ipod, and about pictures and bluetoothe

The Sidekick LX is the same as the Sidekick 3. The only difference is it has a different design and a better screen. You're better off getting a Blackberry instead.
