Need help picking a phone (not for personal use)

[rsarno]

It is to run a specific application, and be sold as a service. No other details can be given really

My requirements are, must be Android, must have bluetooth, and must have WiFi. The bluetooth will be constantly open, and the WiFi will be sporadically transferring throughout the day so the battery is very important also!

I think id have selected the Droid X, if it weren't for that last bit about the battery ...

Can anyone make any recommendations?

Thanks in advance.

PS, extended battery is also fine ... does any one of the devices happen to have the biggest extended battery out of any of them?

Sooo, do you work for the FBI? Lol.....

I'd go with whatever is cheap, and buy an extended battery.
