Custom 'slide to unlock' text on lock screen

[carlosbutler]

In the O2 shop I went into, they had an iPhone 4 and I noticed that the slide to unlock thing when you want to unlock the phone said something different like 'i'm and iphone' or something like that. I have tried to find out how to change it (if possible) but cant seem to. Any ideas?

The phone is jailbroken. There is no way to change it without jailbraking the phone.

If it's jailbroken install "istrings"
