iLike! hey fritz! these are from your phones right? what do i need to do to acheive these effects? play with the settings? i have an n95 and it's 5mp too. does it make any difference if i set it to 1mp setting to save up space? or are these photoshopped/photo edited already? 
Colors here are from the cam itself: user defined: no flash, auto white balance, Normal exp compensation, "Hard" sharpness, Normal contrast, Light sensitivity (ISO) set at High. That's it! I just managed contrast via photoshop because it turned out kind of darker than my liking.
