1.2.1 is the same as 1.2 except it has support for the iPhone and iPod touch when running iOS 4.0. I hope this is useful to you all.
A quick reminder or introduction to those who may have some questions on how to start out, you can look here or send me an email (email@example.com) for additional help.
Thanks for using folder!
Edit: It's now a few days later and while my developer account with Apple agrees with the email I got, that 1.2.1 is live and has been for days, I have yet to be able to get 1.2.1 from iTunes. I'm working with apple to get this resolved, I will let you know when it has been taken care of.
