I seem to have fallen victim of the iPhone 4S wifi greyed out fiasco, which seems to be related to the iOS 7 upgrade. I'm out of warranty so will likely need to get a new phone. I fancy a switch from iOS. I'll probably get either the Nexus 5 or the Lumia 925. I know the Lumia will be much weaker on apps, and Google services are not well supported. I know the camera will be significantly better on the Lumia. Other than these differentiators, are there any other significant ones worth considering?
