soaptestingwsdl
I was looking for some recommendations for testing SOAP webservices. I want to be able to create requests from WSDL, see those requests, and inspect responses. I would also like it to work with WS* compliant services (such as when using WCF wsHttpBinding).
Any suggestions?
One word: Don't.
OK obviously that isn't a real answer. But still SOAP should be avoided at all costs. ;-) Is it possible to add a proxy server between the iPhone and the web service? Perhaps something that converts REST into SOAP for you?
You could try CSOAP, a SOAP library that depends on libxml2 (which is included in the iPhone SDK).
I've written my own SOAP framework for OSX. However it is not actively maintained and will require some time to port to the iPhone (you'll need to replace NSXML with TouchXML for a start)
SOAP - "Simple Object Access Protocol"
SOAP is a method of transferring messages, or small amounts of information, over the Internet. SOAP messages are formatted in XML and are typically sent using HTTP (hypertext transfer protocol).
Rest - Representational state transfer
Rest is a simple way of sending and receiving data between client and server and it doesn't have very many standards defined. You can send and receive data as JSON, XML or even plain text. It's light weighted compared to SOAP.

I use SoapUI (http://www.soapui.org/) for all of my SOAP testing. It's a different client, so it doesn't really help if the client is making a bad request. In that case, I just use the normal debugger or Firebug to inspect the request/response.
