I sent you an email - let me know if you didn't receive.
For posterity's sake... iOS is identical on iPhone and iPod touch. Most of my testing is done on an iPhone 4 and iPads, and in all past releases on an iPod touch as well - as the very last stop double-check before I upload a binary to the store. I didn't discover until the 14th when I was uploading the latest binary, that Apple in its infinite wisdom, had deemed my 20 month old iPod touch unworthy of iOS 5, so this update I couldn't test with it, but there should be no problems. The code makes no distinction between iPhones and iPods. iPad is the only special case.
