Some apps like Iswifter and cloud browse can handle flash by going through an external server?
 
There's another browser app called Skyfire that lets you watch some flash content on your iPad.
 
Photon Web Browser. Best flash browser I have come across so far. Only plays flash when you want it to. I.e. If there is a flash video or what ever that you want to watch, you click a lightning bolt in the top right hand corner and then the web page is converted. This way, you are not having to wait for every web page to convert all the time and you are not hit with flash adverts all the time.
