They are getting there
Stolen / Jailbreak issue aside, I can see where you're coming from here. Looking at my icons of JB software I can see a MMS app, a video recording app and a GPS route map icon. Hidden away is the excellent SBSettings app also.
It looks likely that with 3.0, the need for a MMS app will go. Then possibly TomTom or whoever will bring out their route application. Video recording has also been mentioned in some reviews of 3.0
That takes out three of the four apps I've been using so I have indeed already wondered whether I'll need to JB the 3.0 version when I upgrade...
Noted that I'm on O2 so don't need to unlock.
