Today, we had some problems with one of our sites because it had form elements in an iframe inside of a div on Android 4.0 (Ice Cream Sandwich or ICS for short). Long story short it's a plan it the ass bug that I was only able to get past by reading this Stack Overflow question (http://stackoverflow.com/questions/10232211/android-4-ics-ice-cream-sandwich-iframe-that-contains-a-form). During the debugging process (because I don't have an android tablet [yet]). I found out that Google has an SDK which includes an emulator for ICS. It was super slow (this may have been my computers) and I had to borrow a physical device to work on the problem but it's a good resource if you have Android specific problems:

In case you're wondering the only "solution" to the problem we've found is to dump the iframe; which, while I'm okay with that decision from a design standpoint, is going to be a huge amount of work.
