Hipstamatic has released a new limited edition Nashville HipstaPak which includes a new film and flash. My only wish is that they had created a new "case" based on the new "packaging" for the film and lens. I think it is their coolest yet!
I also saw this article which talks about a resolution bug with Hipstamatic and the new iPhone 4S. Just something to be aware of. Hopefully they will have a resolution soon!
@cheyrebecca I have them all too - my favorite lens is the Libatique 73, which was part of the Cowboys and Aliens FreePak. Not sure if that is still available, though.
Thanks for the heads up!
