What version of iPhone are you using, and what version of iOS are you running? If you update to the most current version of iTunes, you will also be able to update to the most current version of iOS, 6.1, which will allow you to run current versions of apps again. IIRC, iPhones of models 3GS and newer are able to run the current version of iOS.
Even better news: once you update to this version of iOS, you won't have to plug the phone into the computer to update iOS anymore. It can be done over the air, as long as the phone is plugged into a power source. MUCH easier. (If you have questions, let me know in a PM. I'm a nerd, I used to do tech support, and I've done the updates myself, so I should be able to work with you.)
Oh, and I found a piano tuning app that allowed me to see what the Cleanse tone pitch is. It's C5. Here is a table to show which C pitch that is.
