sounds like the reader on the phone is broken/dirty. Try using some canned air to blow inside of the port, if that still doesnt work take it somewhere to get replaced/fixed. If you had any files on the phone to wanted to keep, i use SPB Backup to make sure i have a copy of everything. Even has an option to back up a storage card (for when you get everything working again) Also alot of users utilize Sprite Backup, never used it so i dont know much about it looks like it does the same thing though
