I won't be bothering to update my ipad 2 (jailbroken) any time soon. I don't see the point in why people want the latest when the differences aren't that great. If I do update it'll be when it's a lot more tried / tested and updated to work properly. And obviously when there is an untethered jailbreak for it, if it doesn't happen then I'll happily stick with 5.1.
From watching the BBCs report on the maps, it doesn't sound all too good. No streetview either.
