I have an HTC Hero and I've tried almost ALL of the ringtone apps I could find but each time I try to download a ringtone, it keeps giving me the "Ringtone Download Failed" message and I don't know why. When I searched for help on my phone, I got something about changing my Gmail account back to a Google Mail account. Will this help me and if so, how do I go about doing it? If it won't, can someone please tell me what the problem is?
