Well today this is the second time this has happened to me since I owned the phone. I lost a specific ringtone. One was a "message" I downloaded to tell me I got a text message then I noticed I got text messages with no sound. The message was totally gone from my phone. Today I noticed the ringtone that tells me that my husband is calling me was gone from the phone. I just got a standard ringtone. Any one else have a problem with this?
