I just ordered the treo 300 off Handspring's website, no shipping or tax charges!! Can I change over to the vision plan now? I want to start using it right out of the box. From what I've read on here many people have had to let their treo sit idle for days because of delays in getting a vision id setup.

But not sure if i can change to a vision plan since I don't have the phone yet and they may need the ESN number. Just want to play with it as soon as possible.
