The “Unibody” iPhone – Part II
Wednesday, December 29, 2010
Just over a month ago, I reviewed my iPhone 4 sporting an aftermarket back plate, which I bought from Cellular Nationwide Network. I bought two back plates from them, the regular flat one, and the beveled one which I’m gonna review here.
First things first, here’s what my current iPhone looks like, with and without the Bumper:


Now let’s just get on with the review. Just like the flat case, I find this case exciting to use. And here are the pros that I could think of:
- It feels better than the original glass back plate, and it definitely would not shatter.
- The beveled plate makes it super-flush while using the Bumper case. It’s more ergonomic and lessens the fatigue when holding it.
- It looks superb. I could never understand why Apple didn’t come up with this in the first place. Don’t get me wrong, the glass back plate is also superb, but it doesn’t give that industrial look and class.
However, despite the excellent features, nothing is perfect, and this case didn’t escape that as well:
- The markings scrape off quite easily. You may not notice them in the photos, but I already have a few scratches on the Apple logo there. In fact, if you buy this thing now, they don’t sell ones with the markings anymore. Legal issues as well maybe? I don’t know.
- The screw mounts are just plain weak. Unlike the original back plate, which has steel screw mounts, this one (as well as the other ones from the same seller) has plastic mounts. So basically, screwing it altogether breaks the mount and makes the screws loose. This is where the Bumper case comes in handy.
- Not actually a con, but you might need to know that because of the beveled plate, no aftermarket cases other the Bumper or anything with a similar design, would fit after you have this back plate installed.
- Last but not least, when you are using this back plate, there will be involuntary vignettes and flash artifacts when taking pictures as seen in the example below. Although the flash artifact would only happen when you photograph objects from a half a meter or further.

These rather unpleasant results (which could actually can be useful if you’re a hipster) when taking photos are caused by the gap the back plate creates between itself and the camera lens and flash. It’s too bad because if only they made it flush, this wouldn’t happen. But it is a minor hassle if you can live with it.
There are also a few things to note if you do decide to buy this case and install it on your iPhone:
- First, you’ll need a Phillips 00 screwdriver to open your current back plate.
- If you just bought your iPhone recently, Apple ships them with pentagram screws. A common mistake is that people thought those are regular Torx screws. It’s not and you will most likely break it if you try to open it by force using a Torx or Phillips screwdriver. You’ll need a specialized screwdriver like this one or this one. And trust me, that’s not really easy to find here.
- I do recommend replacing the screws with the regular Phillips screw, because the pentagram screws don’t really last that long after repeated use.
So there we go, my complete review of the beveled metal back plate for the iPhone 4, and I will stress again that modifying your iPhone 4 physically is not condoned by Apple and may break your warranty. Do this at your own risk.
Update:
After further inspections with a different aftermarket back plate of the same type, apparently the flash artifacts was not caused by the beveled structure of the back plate, but it is more of a manufacturing defect. I noticed that the backplate is slightly off-center and this is why the flash reflects back into the camera upon firing. The conclusion is that since this is an aftermarket accessory, we cannot expect it to be in the same quality of Apple’s craftsmanship. So if you got yourself a perfectly aligned back plate, then you’re lucky. Otherwise, well that is something you have to expect from the moment you made the purchase.
