I doubt the service coverage would be that great. It would be like any metropolitan phone service where it only works decent in certain areas.
It probably has a lot of network restrictions where its not as good like only 1g or 2g, etc...
There is a reason its $45 a month. I bet the network it runs on is terrible. If it uses verizon's network its probably still limited to only go so fast or something.
In other words I don't think this is currently possible and I don't think its worth the trouble either. You get what you pay for and I don't think this service would work well if you found a way to make it work on the Moto Droid.
I think experienced coders realize this too, so they probably won't waste their time either.
I flashed my previous smartphone HTC Mogul with CRICKET UNLIMITED service. It's legal. You own the phone. You pay for service.
It was unlimited TXT, DATA, MINUTES. It was epic for the $55/mo I paid for it. Now I pay $120/mo @ verizon for 900 min. The only other option is -HALF- the amount of minutes for $20 less....wish they had a plan to meet me half way inbetween
