How to use jQuery 1.4 without affecting ExtJS 2.1

Hi Friends,

I want to use jQuery 1.4 with ExtJS 2.1 in my project. How can I do that? I read some thing about noConflict() method but I want to make sure that if the latest jQuery I downloaded will work with the adapter comes with ExtJS 2.1 which I believe is for jQuery 1.2.3.

Any clarification on this would really be appreciated.

Thanks
