i erased all data on my iphone 3g. Now it will not turn on and prompts me to dial emergency number. What should i do?

If you erased all data, all you would have to do is to restore your phone. Put it in DFU and try a restore. Erasing your data should not prevent it from turning on. Make sure that your SIM card is properly inserted Charge it on an AC charger and see what you get.
