Look, the "dpi" of 72 or anything else is totally useless. Your camera records pixels, not dpi. You always get the same number of pixels at the same setting. Higher pixel counts, such as 8 MP instead of 6 MP give you more pixelss. The "dpi" value is useless to you unless you choose to use your own printer.

Any decent printing shop will set the equipment to distribute the pixels in the best possible way for the device. The print shop you went to is manned by a complete idiot. Go somewhere else and they should do it right.
