Well for one, the Samsung Intercept only has 256MB of RAM, which is barely enough to handle Android OS and a few apps. Now you expect Flash to run on that? Maybe if you strip the OS down to bare bone then maybe, but the processor must be great.
The intercept absolutely does run flash....well. Albeit an older version, I believe it is 10.1. If I can find it I'll post the link here. If you are seeking flash why not use the skyfire browser (or a few other new android browsers) which has flash built in?
