Number on Logic Board
On the iPhone 4S (UK GSM), there is a number and barcode printed (see pic) just above the digitizer and LCD sockets. Is there any way for normal tech (i.e. not employed by Apple, e.g. me) to utilize this number? I'd like to be able to use it to verify a boards authenticity, for a phone that is out of warranty for example, but not sure if it's possible.
Update: I found that this number is the 'MLBSerialNumber' (manufacturer logic board???) and TinyUmbrella saves it in a file created for an iphone in the .known_devices directory (of TU's specified root for saving SHSH blobs).
Is this a good question?
