The 5MP camera on the Iphone 4 has been bumped up to 8MP, which Apple claims "might be the best camera ever on a phone". It also has a bigger aperture of f2.4, while the illumination sensor has been improved, and there's additional face detection. The video camera can shoot in HD 1080p rather than HD 720p, and it has added video stabilization that the Iphone 4 camera doesn't have.
Can the iPhone replace my DSLR 8MP camera? I think in time they might be able to do that, but for right now no and here are some of the reasons.

You can hear the "noise" on your radio and you will see the "noise" in your photos. There is no grain in digital like we had with film, but the effect looks similar. The more "noise" the grainier the photo looks.

When you can shoot RAW on your camera phone which gives your more control then you maybe able to do a great deal more.
Lens, Shutter Speed and Aperture
Right now most phones do not give you controls over the aperture to change it. You just have a box camera. In many ways the camera in your phone is very similar to the Kodak box camera that they first introduced more than 130 years ago. You couldn't control the shutter speed, the aperture the focus or the ISO on the camera. For the most part this is why the camera phone isn't replacing anytime soon the DSLR or even the point and shoot cameras.
What you gain in convenience with the camera phone you often give up many controls which can make your images a higher quality.
Why I like my Nikon P7000

I can shoot RAW in addition to the JPEGs. My camera offers Fine, Medium and Basic JPEGs where as with most camera phones you have no options. I believe most of them are shooting a Basic JPEG due to the quality I see in them.
I can pick my ISO, my aperture, my shutter speed and I have an optical zoom. My camera phone has none of these options.
Until all these are in the camera phone, the camera phone will be used for convenience, but I will most certainly still want to use my other cameras for images with enough quality to hang on my walls.
