This morning I received my free iPhone 4 bumper case from Apple as part of their free case program. I'm not at all sure how they thought they could charge what they were charging before deciding to give them away. It's made up of pretty much nothing, just a little bit of shaped plastic. Anyway I put it on really just to see what it was like and if it would suit me. I don't have the antenna problem because I firstly don't hold my phone in the way you have to to cause the signal drop and also I have an invisible shield on which includes strips that go around the phone's edge.

Having had the case on all day I can say I don't like it. There are a few reasons for this:

• Doesn't feel right. The plastic is too smooth. It would be much nicer with a more rubbery texture.
• It makes the solid build quality of the iPhone 4 disappear because the bumper moves and flexes to much. 
• The shiny finish does seem to be for style but the edge of the iphone 4 is a brushed metallic look and this takes away from the look of the iPhone 4. Let's be honest the iPhone (and all Apple products) are a lot about image. The bumper just doesn't cut it with Apple normally great design.
• Doesn't fit right. I expected it to be an incredibly tight fit around the iphone but it's not. You can quite easily peal it off the iPhone and I suspect it wouldn't take much to do this is your pocket.
• Won't protect from scratches and scoffs from keys and coins.

It's not all bad. The case should give some protect if you drop it (not I'm not going to test it). It also stops the iPhone 4 sliding on smooth surfaces and that suction effect if the surface is really smooth. Finally, all the buttons are easy to use expect for the switch that turns sound on/off.

When push comes to shove I don't see myself keeping. It doesn't feel right, look good or provide protection from scratches. I'll stick with just the Invisible Shield. If you do have and use a bumper then I'd highly recommend getting an Invisible Shield.
