I created an app a few years back and signed it with a 'test certificate'.
These are only good for (if I remember) a year.
I know the last time it expired, it was a pain to get the app working again.
So, I'd like to know either
A) How to remove this signature altogether and still have the app function
B) Get a 'valid' signature that would be easily renewable and good for more than a year? (presumably I'd have to go to my security guys for this, but I'd like to not sound like the idiot I am when it comes to security, when I make that request).
