Okay, I got an app on my phone that I paid for, hasn't been updated since early 2012. Tried contacting dev through the App Store.... No luck, website is no more. When I open the app my iPhone gives me an error message saying something like this app needs to be updated and my slow down my device. I want to know if anyone would know the process, if it's possible, for me to basically copy the app in Xcode and update it myself for my own personal use of course. I have not ever made an app so I would be learning as I go. Thoughts?
