Yeah good point, I haven't needed tethering yet so I'm all good on that front.
VTEAZN: Yeah Jailbreaking is the way to go, but I really didn't like some of the offerings that were there. Cut and Paste on the JB'd version was rough, of course if apple implement it, it's going to be nicer and better implemented.
But I think I miss winterboard and SBSettings the most.
As for the maps, I think I read that Navman is going to release an app soon.
And I think the same goes for flash, it's been with the developers for a while so I think they're just waiting for it to come out, many thought it was going to be with the new firmware but I guess they're saving it.
I'm not sure if I want flash either to be honest, I may disable it, I think it will just slow down browsing.
