Ok I will try to explain this as clearly as possible, but I'm not totally sure I even understand it.
Evidently I have 2 Apple IDs..one is JohnSmith and one is JohnSmith@gmail.com. When I buy a new app or update on my phone, it has always just been the JohnSmith name without the @gmail.com that I have to enter the password for.
I set up my iCloud, so I had to change the email for the ID to another email (because it wasn't sending the confirmation originally), so now when I download an app, the JohnSmith@gmail.com shows up...and this is also what lets me in iCloud now.
Is this ok? Will I lose my app purchases or anything? I'm conerned that since the @gmail one shows up I've messed something up.
