Taking pictures with the curve can be very tricky. Fort those 2 shots posted, yes you need more light or you need to hold the phone completly still. The slightest motion will cause blur. The orange tint is what happens when there is not enough light, as posted already it's noise.
These pics I took with my curve:
Less light
Please keep in mind that these have been resized. If you want links to the fullsized shots (i think I only have the first photo full sized), let me know
