By default, Windows Mobile HTC HD2 will have auto selection on the network band ~ 2G (GSM) and 3G (WCDMS/UMTS). However, I don’t have a strong 3G HSDPA signal at my place. And it will switch back to EDGE or GPRS whenever 3G signal dropped below 1 bar. This is really annoying. Is there a way to make it stay at 3G HSDPA permanently? Yes, here is the step by step guide to fix it.
