The iPhone 5 has arrived, and the company is claiming the device is “the biggest thing to happen to iPhone since iPhone.” Huh? That awful slogan aside, the oft-leaked and rumored device is finally here: 4-inch screen, LTE, new dock connector and slim build. This really should have been what Apple announced last year, but hey, better late than never. Honestly, the build and quality is still top of its class, coming in at 18 percent thinner and 20 percent lighter than last generation. However, we’ve seen and heard about some mightily impressive handsets coming from other manufacturers — Lumia 920, Galaxy Note II — meaning Apple’s iPhone 5 is going up against its biggest ever competition. How will it stack up?
