For my app (NubiNews Reader), memory footprint on the javascript side is never an issue. Maybe it's because the JavaScript files that I execute each time is less than 1000 lines (or less than 50KB).
I pass Java Strings that are up to 300KB to the JavaScript side, where I would run a lot of string processing such as regexp, split, concatenation. Again, no problems there. It seems like WebKit's memory manager is quite good and I never got any out-of-memory due fragmentation despite my excessive string operations. On the other hand, I got more memory problems from the Java side. Because the Java heap is not compacting, if I cache more than ten 300KB Strings (the total of which would be just 3MB max), the Java heap could shoot quickly to 16MB and cause OutOfMemory on the Java side. Coincidentally, the WebView on Android is much more stable than iPhone's browser (even OS 2.2). I can routinely display pages with up to 100 VGA-size images and never saw any issues. On iPhone, if I view such pages, the phone crashes routinely. I am actually planning of porting my app to iPhone. Could you tell me a little about the kind of issues you found on iPhone?
