  Does this method require the purchase of a $99 ID?

  

  Community Answer

  No, this is completely free. The only time you'll ever need a $99 ID is when trying to install developer tools, which includes things like developer iOS betas.

• Question

  What do I do when it doesn't work?

  

  Community Answer

  Try asking the developer. It could also be other apps on your phone. Try deleting some of the apps that take up more space.
