We are currently loading 2 different versions of jQuery on our page, 1.4.2 and 1.10.1. The $ and window.jQuery objects are currently pointing to 1.4.2.
We are using no
If you load the bootstrap JS straight after loading jQuery version 1.10.1 and then put jQuery into no conflict mode, it should work.
e.g.:
jQuery.noConflict(true) will reassign both $ and jQuery to their previous values so it doesn't matter if version 1.4.2 is loaded first or not.
It does mean your users will be downloading jQuery twice though and you will need to remember if to use $jq1 or $ when doing anything with jQuery.
