how do you get the speck gemshell case off an ipod touch 5th generation

I am trying to get the speck gemshell case that I purchased along with the "new" ipod touch 5th generation. It seems like a solid piece of clear see-through piece of plastic and it will withstand lots of drops with the added "lips"on the front of the ipod touch (one reason why i got this case. The other reason was to have my red ipod seen by all who wish to look at it.) but my problem with it is that it seems "too solid". The case is hard to put on and REALLY hard to take off. I have read on some websites that you can take a credit card as a way of taking the case off but I want to figure out how to take it off without ruining my ipod or bending the case?
