You can actually make a web service and make it real easy to integrate into your iphone up. I would suggest if you are using .net to create a WCF service with webHttp bidding and implement get and post methods, you can get responses back in json and xml (theres a set of classes to parse Json on the iphone that will make parsing the response a breeze, they are avaialble in the web), with little setup you will be able to perform gets and post from the iphone using NSURLRequest. Heres an article that talks about making a restful wcf service http://www.developer.com/net/article.php/10916_3695436_2. Its also very easy to add authentication and security to your services with WCF.
