As I already said...

*For those(like me) who have the Error 28, the problem is a bad dock connector on the iPhone.*
*You Must replace it.*

Was your iPhone resolved by this? Someone told me that it needs replacement on communication board, and it costs a lot! =(

just seeing if you made any head way in this although I do not see any damage in that area I would be willing to look into that first

error 28. hardware problem. it means that your battery is not charging. take your phone apart and insert a freshly charged battery. then restore.
