You should find your image in your Assets-folder and check with Inspector what are the Max Size and Format -settings. If Max Size is smaller than the original image, it will be scaled down. In addition compression lowers quality but requires less space. It is also possible to use different settings for different platforms so that is probably the reason why they look fine on Windows. If you still have problems could you please give more information such as what kind of image are you importing and what import settings have you tried.

EDIT : In addition check that on the iPhone settings -tab "Override for iPhone" is not checked. Also you could try to make your texture size power-of-two for optimization. Sprites can not be generated for non-square textures in RGBA Compressed PVRTC 4 bits format.
