who cares. does the same thing. You can do it manually if you want too by editing /var/mobile/Library/Preferences/com.apple.springboard.plist and adding a key called SBFakeCarrier and the value as whatever you want it to show up as. thats what both of them do.
Always up for a bit of manual tweaking, what prog do I open the .plist file in Windows? I tried the usual notepad, wordpad etc but just a load of characters.
EDIT
should have searched this forum first haha, found a post with a link to a tiny editor
