How to link to apps on the app store
A few web searches yield all sorts of contradictory advice on linking from an iPhone app to an app on the store. Here are some links that come up, together with comments from testing:
http://itunes.apple.com/us/app/anagramania/id360016055?mt=8 -- works great. But is it US only?
http://itunes.com/apps/anagramania -- works after a bunch of redirects, which are likely to annoy the customer.
http://phobos.apple.com/WebObjects/MZStore.woa/wa/viewSoftware?id=360016055&mt=8 -- works great. But Apple appears to be trying to remove "phobos" links from its documentation.
http://itunes.apple.com/WebObjects/MZStore.woa/wa/viewSoftware?id=360016055&mt=8 -- works great, but Apple's documentation mentions problems with similar links. Apple doc here: http://developer.apple.com/iphone/library/qa/qa2008/qa1633.html#STANDARD_APPSTORE_LINKS
Can anyone bring order out of this chaos?
