Hi there and welcome
Did you ever make a backup of the iPhone with the content your now missing?
Please let me know
ok, then it will not be possible to restore sorry, as you overwrote the date with the backup which wipes everything, its not like deleting a file, but your also overwriting it
I am really sorry but when you do this the data is completely gone.
I am really sorry about this, and if you have problems, or would like any additional information or assistance, please do not hesitate to let me know.
And if you can take a second to rate my service, that would be greatly appreciated.
