OK - I have tried everything. Turning the phone on and off. Rebooting my PC. Done both of these multiple times. Have changed settings in "Connect to PC" and re-set them to see if that would make a difference and have clicked and unclicked "Ask me..." option on connecting. Nada. What is going on?!! The phone just starts charging, but I cannot get it to show up as a drive. It worked perfectly until I installed Handcent SMS (which I've since uninstalled). And have naturally rebooted the phone several times since.... yet it still doesn't work. I'm really at my wits end. I'm using the USB cable that came with the HTC car charger - but it surely can't be that... but then what is causing it to not work? The only non-standard things I have on my phone are 3G Watchdog and the Astro file manager. Both of which didn't have any impact WRT to mounting the phone. But now, having just bought some music from Amazon on my phone, I can't get my music or photos off the phone onto my PC. Help!
