Can you change the carrier logo on a T-Mobile iPhone 5 without jailbreaking?

So all of my friends have insane carrier logos/names like 'Batman' or some kind of image. And of course, being the peer-pressure-y person that I'm, I gotta fit in with them.

I was wondering if it was possible by any means (except jailbreaking) to change the logo on a T-Mobile iPhone 5? I downloaded CarrierEditor 0.0.6 but it did not have the T-Mobile USA package in it… Probably because at that time, T-Mobile was not officially supported by iPhone.

Is there, perhaps, an updated version of CarrierEditor with T-Mobile USA on it, or maybe another… Thingy that could change the carrier logo WITHOUT jailbreaking? Of course, this is not a huge must-have thing, but I thought it would be cool to change my carrier name to something witty, maybe like to 'No Service' so it'll say 'No Service' with bars on it… Which I guess would be kinda funny.

Nope. Though you could try screenshotting the lock screen, editing the text in Photoshop, and then loading the image on the gallery app.
