The anntena thing is a flaw with an easy fix right now, probably even bettered for new phones. But yes, it was a glaring oversight. Lets not forget this is another Apple invention with pushing/testing such innovation as they do there are bound to be teething problems.

The yellow spots is a non issue as the inventor of the yellow glue has already said its from being rushed off the manufacturing shelves without being given time to set and will dissappear in days (as has been reported by users).

Thats it as far as I can tell? Or would someone like to enlighten me
