I've yet to pay for a app on ipad but was wondering if there is any way to gain a refund if it doesn't work? I have downloaded several free ones that don't work so I'd be annoyed at paying for something that doesn't work! I've also found several of the so called free ones are simply time limited trial versions that stop working after a time & there doesn't seem to be any way to re install them as they somehow know its the same ipad! how does that work? can't you clear your cookies like a PC or something? sorry this is now 2 questions!
