Ah, yes. I actually did try that once or twice, but I must have misclicked. Thanks.

And I'll assume I won't be able to transfer my progress then (at least without root). Oh well.
Hello again. I am trying the do the unlock code on my Galaxy SII but it doesn't seem to work. Is this only for Kindle again? I've tried clicking on the first plaque for each year listed, and I've tried clicking on all 3 plaques for that year, and I've tried restarting the app in between attempts.
Thanks for your help.
broadle: Thanks for the info. I will lose access to my device when I switch. Are there any files I can copy to preserve the data until an update is made? (I am using a phone though, not a Kindle.)
