Hi, this problem happened to my mom's phone and I'd really like some help. Out of nowhere her phone started showing many 'force close' messages, so I decided to restart her phone. It froze while restarting, so I took the battery out to shut it down. It started up normally, but now my mom lost the music ringtone we bought for her. It's not under he list of rigtones when I try to set it back. I'm sure it's still on the phone, but it's not showing up. How do I solve this without buying the ringtone again?
