I ordered a iPhone 6+ on 20th September and it's still stuck at "processing items" i wonder if its worth calling Apple. But then again, i have read that they are having trouble keeping up with the demand for the 6+ because more people are buying it than they had anticipated. Apparently 60% of all sales.
I think most will return their 6+ phones for the smaller 6 once they realise its not that practical for everyday use. Its a novelty so people want to try it.
