Short answer: No.
Long answer: We are hopeful that this project and iPhone 4 case product line become a resounding success so that we can expand our offerings to other devices, including previous generation iPhones, iPod Touch, and maybe even the iPad!
In the meantime, we invite you to fully explore the DNA Case project, and if you don't have an iPhone 4 but know someone that does, this would make a great gift!
Of course, pledges of any amount are appreciated! ;-)
