What is the difference between jQTouch & jQuery Mobile Framework ?
Are they related (other than being both based on jQuery) ?
Do they have the same goal ?
As I discuss on my blog post:
http://zsprawl.com/iOS/2012/04/comparing-jquery-mobile-vs-jqtouch/
I find jQuery Mobile a lot more feature rich and with a lot better cross platform support. JQTouch is very lightweight and great for "form-based" apps that just need navigation. It is missing a lot of the features that users have asked for, and have been turned down, like fixed footers and tabbars.
For detailed understanding and to know the differences between mobile frameworks,
you can consider the following link.

jQtouch is optimized for WebKit, jQuery Mobile is looking to support all mobile devices; that is my understanding

Additionally to Aaron's answer this is what I've come up with so far:
Apps developed with jQTouch will certainly run fine on iPads and other tablet devices, but we aren’t going to automagically convert to a more tablet-friendly UI that takes advantage of the additional real estate. If you are in need of a JavaScript library that magically updates your UI for everything from small screens, to tablets, to desktops, check out Sencha Touch.
