How do I use a newer version of jQuery with Ubercart shipping quote (Ajax)? If I use any version of jQuery with drupal/ubercart other than jquery 1.2.6, the ajax comes back from (UPS,Fedex,etc), but never updates the objects on the screen.

How do I use a more current version of jQuery with ubercart?
As it turns out, Ubercart will NOT work with jQuery after 1.2.6 unless you make a small change to an Ubercart module

ubercart/shipping/uc_quote/uc_quote.pages.inc

Go to around line 70 which should be the end of the uc_quote_request_quotes function

comment out or replace the broken drupal_json($return_quotes);

replace it with the standard PHP json encoder
print( json_encode($return_quotes) );
