I'm having a terrible first world problem: I want to use both Nexus 4 and iPhone 5. It's literally making me insane. I currently own iPhone 5 but each time I read Nexus reviews, I want to get Nexus 4. I can't use both as I have just one phone number. Perhaps I'll get Nexus 4 and just switch the sim card around. That's terrible. ARGH.
