Apple have some big decisions to make. The iPhone used to be the best phone you could get. The 4 was probably the best phone they made, trouble is they have stalled.
They have to change their user interface, it simply cannot stay as a screens full of icons, they are being left behind by Android and Windows.
The maps fiasco will see how much Apple values their users. Let Google get their maps app out to help the iPhone users while they sort out their own version and a lot of users might forgive and forget. Make them soldier on with the useless version in IOS6 and they will burn a lot of bridges.
