Welcome to the forum.
It can be a little confusing at first. Do a lot of reading in the threads that are posted. More information here than most places. The phone has lots of hidden menus that you find by touching and holding as well as the menu button on the phone.
Welcome, and I must say that you will find yourself spending a lot of time in this forum for the next few weeks. I believe this is the BEST forum for Moto Droid owners and includes a wealth of knowledge and information. Congratulations on your purchase, you are going to absolutely love your new phone
