I am looking for a GPRS+GPS arduino device. I have tried one from cooking hacks and have not had much luck with it.
I have the following requirements.
1. must be arduino compatable
2. must work with att or verizion
3. needs to have add on antennas.
4. needs to be able to have battery backup
It would be nice if......
