With our T Mobile contract finally up, we were free to join all the happy people and get iphones. We've only enjoyed their greatness for a week or so and haven't even found more favorite apps, but they've been invaluable on this weekend's road trip. With the maps feature we didn't have to guess where we were and we didn't have to print out directions.
Even in the middle of the woods we were intermittently able to check our email. Soon I'll forget how I was able to live without it. Mine is named Hot pants.
