From the outside of its white box, labeled "Phone no. 4," it's clear to see that the Air Phone 4 is trying awfully hard to be an iPhone 4. But then we already knew that. How does it compare to the real thing in the real world? Not well, according to intrepid reviewer Stuart Ashen. The external metal surface (which you might be familiar with) is here actually plastic, so you don't have to worry about dropped calls if you fondle it the wrong way, but the phone is said to have awful signal regardless -- despite showing full bars even when missing a SIM. Ashen concludes the thing is an "astonishing bit of copycat work" held back by "the worst touchscreen ever." (Yeah, it's resistive.) Oh, and that Facetime app we spotted before? It "doesn't seem to work properly," about the kindest thing that can be said about this junker. If you'd like to see the full (and thoroughly entertaining) review, it's embedded for you right after the break.
