My RN2 is dying, thinking to change to RN4 (official MY set)

but I saw the spec, wifi AC dun have??
even my RN2 supports AC leh, can anyone verify theirs?

Gotten my black N4 last week from 11st with freebies (case, tempered glass and 16gb card)
The free tempered glass is white, so kinda useless for my black N4. So I went out to look for one at few mobile phone shops, surprised I couldn't find any, as the existing N4 glass doesn't match my screen, either its too small or the cut out holes for the speaker & camera doesn't match.
Seems the size for international version and China versions is different.


So far feels no diff in terms of handling compared to my old N2, but one thing I'm pretty impressed is the batt life.

Previously my N2 can only last half a day with moderate usage, now it can last a full day.
