hi, I have 3 apad's and i have just teseted a theory. I install and run the app after turning on my brand new apad for the first time. It works. App is running. Now i factory reset using the options. App wont run at all. The reason i had to factory reset becuase i had issues with android market - i tried downloading apps and i always had the message saying: Download unsucessfull. So i factory reset. but the app i have on my SD card wont run now. So i tested this on my 2nd apad and the same result. I even flashed them with firmware from HIpad and custom firmware from here. ANyone has any ideas??bought mine in the UK from http://stores.ebay.co.uk/DigiBites - great devices with metal case))Otherwise i am happy.
