Anyone know how to change the carrier name on ios 5.0.1 without jailbreak?

[Primetime]

I've already tried a method listed here on the iPhone 4 forum but the method doesn't work on 5.0.1. Tried it, I'm adept at these things and it simply didn't work. Didn't damage anything or lose anything either, it was as if nothing happened. So does anyone know if there is a way to do it for 5.0.1 yet? I don't want to jailbreak my phone, but a little surprised I can't find anything on how to do this for those of us running the current up to date ios. Scoured the web and coming up empty.

Let me clarify that I'm looking for a method to do it without jail breaking the phone. Thanks all.

Without jailbreaking the iPhone? I don't think there is a way.

There is a way for iOS 4 and so on. It's pretty simple actually just a plist code you write in. The problem is there's no way to do it on ios 5.0.1 yet, that I can find... I was just wondering if anyone knows yet. You're not actually changing the carrier, you're just changing the name to say whatever you want it too. The carrier actually stays the same as the current one you're using.
