Yesterday my HTC Hero frooze up as I was looking through the AP News app. I tried pressing the power and return buttons to get out of it but it wouldn't respond. I ended up letting the battery to dead and then plugged it back in to power up again, allowing the phone to reboot but I was hoping someone out there knows of a better way of dealing with this? Chances are it is something really simple, but I don't know what that is. Thanks.
