oops sorry I didnt mean to change the subject.
If the Messages that were deleted were part of regular iPhone messaging service then I think they are permanently deleted not unless a software like the old Norton can actually restore them? But if the messages were part of other programs like Viber or WhatsApp or Tango etc, then the messages store on their website some place and as the admin person you will have access, although I dont know how long the msgs will be there?
umm I dont know if Apple does the same thing? I am sure they save the msgs up on a server some place...I know all the communications in USA (at least) go thru 2 israeli companies in tel aviv and some other damn placeFox/SkyNews Brat Hume and Biran ??somebody reported that not me). But I dont think Apple would give anyone access to their spy servers.
The easiest way to get deleted msgs back is to ask the person whom you were conversing with, lol cuz if you have problem with them then forget it...you'd have to physically steal their iPhone and then their PIN to get in it
