How to call SOAP web service with Android

I am having a lot of trouble finding good information on how to call a standard SOAP/WSDL web service with Android. All I've been able to find are either very convoluted documents and references to "kSoap2" and then some bit about parsing it all manually with SAX . OK, that's fine, but it's 2008 so I figured there should be some good library for calling standard web services.

Is Google the only OpenID provider that requires "identifier_select”?

I am developing an OpenID consumer in PHP and am using the fantastic LightOpenID library ( http://gitorious.org/lightopenid ). Basing my code off of that found in the example client script I have successfully created a consumer. However, I've run across a snag: Google requires the openid.identity and openid.claimed_id to be set to "http://specs.openid.net/auth/2.0/identifier_select" (see here ). If I do that it works but other providers (i.e. AOL) don't.

Is there a better way to embed maps on the iPhone, without using native code?

I have an iPhone application, which does include maps. However, when a user clicks a button in the app - it just brings up an embedded safari browser, with the Google Maps in it.

Also, it includes display of a polygon and pins.
