start a new thread. Way offtopic.
EDIT: Well... I guess not completely since you are actually talking about starting this app...
but honestly more generalised tests will probably serve you better initially.
I would go for a new thread entitled "Is my device properly Jailbroken? Apps failing to run..."
Also: your device is listed as "Kindle" it would be helpful to mention which one
well, sorry I can't think of anything more constructive to add.
Hope it works out.
