Short answer, no.
First, PDANet is only for USB tethering. If you have a rooted Android device, get WiFi Tether. Free on market. And does not need for iPad to be jailbroken to use it.
If you get iPad 2 now, chances are that OS version on it will not allow jailbreaking, you may have to wait for new OS to be jailbroken. It can happen within next week, next month, next year, or never. Nobody knows.
