This is the nature of jailbreaking. It uses operating system flaws to remove restrictions. The more exploits get patched, the harder it is to find new ones. The person who got the latest A4 5.0.1 untethered jailbreak said it took months to find the exploit. They are working on an A5 version but after Apple patches it in 5.0.2, they have to start over again.
All Apple really has to do is make it futile to keep doing it. They are doing this in two ways - by improving security, which is good for everyone and by implementing features that people use a jailbreak to get.
Yes, some people still want free 3G tethering and...
but they aren't all that important to the usage of the device. It's not as if you can customise other systems entirely either. Android claims to be open but how do you change the number of home-screens? You can't get rid of the home screen and just list all your apps. You have to replace the stock Android system with custom ROMs.
As soon as you make more compromises by jailbreaking than gaining benefits, it will die out. Less than 10% of iOS owners jailbreak their devices because they are probably satisfied with what the stock system does and don't want to risk voiding the warranty on a $500 phone.
