If you are having problems launching MW after upgrading to iOS 6 read this: It seems that deleting and reinstalling, even a hard reboot, is not solving the problem. MyPark emailed and said an iPhone Restore through iTunes solved the problem. As long as you backup your phone first and confirm the backup was completed, a Restore is actually not that hard to do. HOWEVER please remember this could cause unforeseen problems for you, especially if you don't know what you are doing. I hesitate to recommend this as a solution. Before trying a complete Restore, try to clear your Safari cache by going to Settings>Safari> then click on the "clear history" and "clear cookies and data." Please note this does remove any settings you have in Safari. I think this is a glitch in iOS 6, because each time Apple has updated iOS, apps built in previous versions always work. Let me know if you find anything else that works. Thanks!
