I have had the Sprint version of the HTC Hero since March of this year. Since then, my phone has stopped receiving texts at least 4 times. the first time it happened, all tech support could tell me to do was do a hard reset, which I have done each time this has happened with no difficulties. Last night, I reset my phone, but when I turned it back on, it couldn't connect to a mobile network. Once I got home, I tried connecting to Wi-Fi and had even less luck. Every time I toggle my mobile network, wifi, or airplane mode, the phone connects to the network in question for about 2 seconds and then immediately diconnects. Any thoughts?
