Im not here to lambast the creators of this app, just saying it does not work for me on either my iPad 1 with 64GB or my iPhone 3GS with 8GB. I have reinstalled it twice on both devices, making sure no other activity was occurring on them, not even push notifications or text messages. Yes, the app page says it is "optimized for iPhone 4", but it also says it is supposed to work on my devices. On the iPad, it does not even start, and on the iPhone, it starts, but graphics are missing and just has a little blue box with a question mark in it. Not as handy as I had hoped.
