I'm installing it right now. It was a bit of a disappointment when they announced multitasking wasn't coming to the 3G, but unified inbox and folders are a big plus. It will tide me over until I get my iPhone 4 on Thursday. If I wasn't planning on getting a new iPhone soon, I'd definitely be more disappointed. But with only 128MB of RAM, it makes sense why some things aren't coming to the 3G. I'd rather spend the money on a device that will run the cool new features well.
