Where have you bought your HTC Hero from? If you have bought it outside the Americas your Hero is very likely to support 3G at 900 and 2100 MHz only, which means it is incompatible to the frequency bands used in the US (850, 1900 and 1700/2100 MHz). In that case you would only be able to use 2G networks, which means nearly unusable slow data speed.
