iphone: basic understanding of google map api

ok let me admit something that I am a little bit lost in here

Can any body suggest me some startup tutorial to get some idea about google map api. I tried this url

"http://code.google.com/apis/maps/documentation/javascript/examples/map-geolocaton-iphone.html" as mentioned in google map api documentation

but this url has 开发者_高级运维been moved I guess so Please suggest me some tutorial with

1) show basic google map (not mapkit) 2) show pins on map 3) show multiple pins on map 4) When user clicks on these pins something get displayed in some subview

if you are building a native app then you can visit my blog post here for mapkit (its great!) http://www.makebetterthings.com/blogs/iphone/add-maps-in-iphone-apps-mapkit/

if you are building a web based app and needs javascript / html tutorial then you can visit -
