You have to love it when apple releases a very early beta for developer testing only, and specifically states that the maps app has very little content at this stage but more will be added later, and still a ton of people brand it a fail and complain that their location isn't available in 3D yet 😀
It's like Da Vinci showing somebody their first sketch of the mona lisa in private, then the public seeing a screenshot and criticising him because it totally lacks colour + detail.
Wait for the public release. If it's still like this they deserve a serious kicking (never mind the content, the crashes are worse!). More likely they'll have fixed the majority of the issues and 3D will be available in a lot more cities 😉
