Android OS 2.1 increases it to 5 homescreens. In addition, you can put folders on any of the Android homescreens that work almost identically (from what I gather from the description in the article) to the way folders work in iPhone OS4. I think others have mentioned that you can get 3rd party apps for Android that increase the number of home screen to at least 7. These do not require rooting or anything else unusual, just a quick download from the Market.
