At the Mall here in Rio de Janeiro found a store that sold mobile covers. These below, more cute, cost 39 real!
How about buying for just over 6 U.S. dollars? Just go on Dealextreme! This below cost $ $2,70 and have the same quality of store.
The dust cap from the store was for iPhone, But if you have a Galaxy S3 has no problem, has for several types of cell phone and for the same price.
The cover has buttons on the sides that fit perfectly to the buttons of the phone. It was very good and stylish!
Below the USB connector perfectly embedded in silicone case, that is flexible and avoids damage caused by no.
The only thing I found a little problem is that the cover makes the boxy mobile, IE, the curved design of the cell phones Samsung. Even so, It's on.
I leave the link to this cover in DealExtreme, and also a list of other silicone covers for Galaxy S3:
