After reading another thread about their faulty wi-fi signal that commented on the model no. of his ip5 beginning with ND, I realised that mine begins with MD.
Has there been a recent silent hardwrae revision that probably changed the wifi contained in the ip5?
If not then why the sudden change of the prefix in the model numbers?

No, the only difference in my experience is that retail units are MD and white-box replacements done at the Genius bar are ND.

So the replacement coming to me in the mail with a MD model is a retail box unit ? Has anyone else with white box replacements have a ND model ?
