I have had my nokia c1-01 for almost an year now but of late it has brought me nothing but problems. When i begin a conversation, many more conversations form themselves and even some that i have never had. Then i try and delete them but i receive a message, "Error occured. Deletion not completed." The worst part is that when i try to open the conversations, the phone restarts all the time. I have tried to restore all from factory settings but even when i do this, they still come back. Please assist
