Well mine arrived on Friday and I've been playing around. Not put my sim in yet because imessage refuses to turn off and I don't want to miss messages.
I've got a 311 which I think means its not got the revised speaker holes and buttons. They don't seem loose and its loud enough for me. Is it worth returning and exchanging?
I just returned a 312 and the speaker holes were the same as my 311. And in fact the mic holes o my 311 were bigger than than the mic holes on the 312. Beleive it or not, the 312 had two different size holes but it is a very slight difference but you can see it if you look hard enough.
And the screen on the 312 had a little bit of a yellow tint to it compared to the 311.
I wouldnt return it if it doesnt have any issues.
