How do I get around the email Apple ID problem on iCloud?

Question

My Primary Apple ID is not an email address. After following Apple's prompts on my iPhone after installing IOS5 I (and I regret this emmensely), created a new ID with my primary email, the same one that is the email linked to my other Apple ID. It allowed me to do this.
Since iCloud would be fairly unmanageable on my iPhone and Macs with 2 IDs, I'd like to figure out the best way to trick the system to merge all this mess into one account.
Here's my problem.
My primary Apple ID is a simple username.
The email for it is my primary email
The secondary Apple ID account I created for iCloud is that same email.
The email for it is that email.
What I want to do is change my primary Apple ID with the username to the primary email name, in order to make all my iTunes purchases synchable with iCloud.
I do know that Apple does not allow an ID to be cancelled, so I can't go this route to get rid of the current email one.
Dropbox? ;-)
TIA

Answer 1

I signed to iCloud using a [email protected] email address as the username. It's the same email address as my primary ID's email.
The problem is not buying apps or music using the iCloud ID, it's managing them later.
You'll end up with a big mess of apps and music all over the place. You won't be able to sync to iCloud all the music you have on your primary ID.
I made the mistake of buying an expensive app using the iCloud ID on my phone, only to not have it be able to sync to my computer, which uses my primary Apple ID. I had to go through Apple to have them void that purchase and buy it again using my primary Apple ID.
All my issues would have been avoided if Apple had allowed me sign up for iCloud using my current Apple ID.
It's because of their requirement that the ID username needs to be an email address.
