Can I save my htc desire if the battery is dead? I ran my HTC Desire on a 0% charged battery - and it shut it self down. Now it won't charge anymore and wont start even when plugged in.

What are my options?
How long have you left it charging for? If it hasn't been long (a couple of minutes then your phone is probably fine). Connect the phone to the mains and leave it plugged in (don't try to turn it on) for about 15 or 20 minutes. It should start up then.
