Covering the back of the iPhone won't make a difference to your tmobile signal, I guess you're just in a bad area for tmobile

a bumper with a back =/= not a bumper

that's called a case, and there is no case that will improve your reception

but avoid all the aluminum ones, most will degrade your reception

i though case would help improve signal like bumper
look like both is cover round of iphone ,

If you have a big amount to spend, take a look at these bumpers If not, ebay it's your best friend.

The products on that link look awesome but they certainly are a bit steep!

The bumper I have works better than nothing. Still it's a terrible antenna design, one that I'm hoping Apple abandons on the next iPhone model.
