Please Help. ThanksHow can I clear my default notification sound/ ring tone on my htc hero?
I have used the ventones site as well for my free ringtones





well, you need to connect the phone to the computer first, and make sure that you insert the memory card first. After you do that your phone should ask you a few options like Mass Storage (i think). Then you will want to use Windows explorer or your My Computer icon to drag and drop the file over. These are the exact instructions that i found for you from other people that have used Ventones for their LG rumor 1. Don't know about the 2nd version














Step1


a) upload an mp3 file





step2


crop the file to however many seconds you want with their free online ringtone maker





step3


after you finished making the ringtone (don't press the send to phone button)


click on the ';sprint customers without internet'; button





step4


that will take you to the


FREE SPRINT RINGTONES WITHOUT INTERNET PAGE





step5


click on a link in the middle of the page





step6


wait a few seconds and then you will see a link to download the new specially formatted sprint ringtone file





step7


transfer that file (it should be in .3g2 format, NOT in mp3 format) to your dcim folder (memory card).





if that didn't work, try making the ringtone again from a different mp3 file, maybe the mp3 file was corrupt
