you still can use backup to download all app to itunes(pc) and use itunes to install the app into new phone lol

same here.

i just got my iphone 6s plus .. smooth and nicely..  and why can't download the CPUIdentifier ? say unable download app.. any clue ?

Hey thanks! Woah okay... I just sold my old phone means I won't have any phones for that period already if i exchange...
Thanks! I don't want a seed unit.. I last time exchanged an iPhone 5 and I got one with SUPER poor battery lif... but maybe I'll try to send back during the last month of the warranty.
Thanks for your suggestion! I am thinking that too. The unevenness is not very severe hence I think I'll go with your way by sending after a few months. I don't rhave good impressions with the refurbished units because in the past the exchanged one are always scratched. I would opt for a box to box replacement anytime but guess it is impossible now..
Hey thanks for your information! My dad got it for me and hence.. But I didn't notice the unevenness until I read a thread at Macrumors and oh fml my phone also have this issue. haha but I just checked the store at Machines and the display units there are uneven too.. all the displays are slightly darker on the top left corner.  they say its because of the 3D touch but.. well. :l Guess I'll take it back after couple of months.
