Anti-Osama message infects '3 Handser'?

The Inquirer presents a puzzling story about a 3 handset user who claims the screen on his NEC616V 3G handset has been infected with a message reading… "British Bulldog get Osama!". The thing is that he can't get rid of it. He actually contacted the '3 Contact Centre', but was told that this was a virus that had "infected the whole network since Sunday daytime." It's a unlikely it was a virus since technically speaking you shouldn't be able to get a virus on 3 (UK) as it is a totally enclosed system. The INQ thinks this is a version of the old "operator logo" gag: you are tricked into accepting a text message, which then replaces the operator's logo - in this case 3- with another graphic. The INQ source is adamant that he didn't accept any dodgy text messages before Osama made his appearance. 3 UK are investigating this.
