Sorry, that was rather vague. Yeah, it's not. BUT, I remembered that I didn't even install it, so it may be down to my ignorance. It's in my little 'app bin' or whatever in iTunes and just fails to be transferred across when I sync. I'm guessing I'll need to transfer it manually or something.
 
Jailbreak is no problem. IOS4 the 1.4 works but it removes your favorites, stored routes etc. The 1.41 update fixes this.
