I have a SanDisk Cruiser 8 GB flash drive that will NOT work in my A500. I traded temporarily with someone in my office because his 8 GB flash drive works fine in the A500. He doesn't want to trade permanently. I need to buy another stick, but I want to be sure I order one that will work with the A500. Any recommendations? If you're able to use a USB flash drive with your A500, what is the brand. Thanks!
