Hi All, thought chiming in here was interesting enough to finally join the forum:
I bought the KSO because I frankly *like* the concept of the ads, and because I figured amazon would either make them good or eventually ditch the program. But that doesn't mean I can resist the urge to play with it and see what happens
I replaced every special screen saver .gif with my own, and as someone mentioned, it worked fine-- at first. Then, when I eventually rebooted the device, it must have detected the issue and it refused to show any special offers at all, either on the home screen or screen saver or the "view offers" option: it just showed a placeholder image with an image of letters (printing press?) and a message to connect to wifi to view special offers. Interestingly, connecting to wifi and hitting refresh didn't change this until a day had gone by, and suddenly it worked again, reverting everything.
