Even though this device has 2.2, indeed as stated previously the problem is that the version of flash available for android was not written to accommodate this lower end ARM processor (I have the same problem with my Optimus phone) so it will not work - without a processor upgrade. That is the major knock against this tablet (that and lack of onboard storage memory) - otherwise it would be a great tab overall. I'll try to find a link to corroborate or refute this claim. I read it somewhere just can't find it at the moment.
Edit: Here is a thread that seems to conclude that Flash will not run on a device with an ARM 11 proc
