One thing I really missed when I upgraded to my Bold 9650 was the ringtones on OS 5 when OS 6 was released. Thankfully, the link to download them has been available on the BlackBerry mobile site, but now access to the download is even easier through BlackBerry App World.
Another odd thing about downloading the ringtones from the mobile BlackBerry site, is that when you upgrade the OS or upgrade the device, the ringtones don’t move, which again you would have to go to the site and redownload. Having the ringtones available on the BlackBerry App World makes getting those ringtones even more convenient. I have a few faves from the OS 5 collection, especially BBRelaxed_StarChime.
If you loved and miss your ringtones from the OS 5, download them free out of BlackBerry App World and enjoy.
