Programatically login to "MyPage"

I want to make a scraper that logs into mobile providers' "MyPage" on behalf of users in order to retrive their usage pattern. Their individual usage pattern will then be used for a price comparison between providers (this latter part is not a part of this job). The user will provide the name of his provider, his user name and password to the "MyPage"-facility his provider offers. I am starting with the Norwegian provider OneCall, where I am customer myself: [login to view URL] I have not been able to succeed using Curl, probably because there are tokens, ajax, hidden login addresses etc. in play, things I don't fully understand. I am not in a hurry with this task, but want to do it during 2-3 weeks. Preferably, a provider here will not only make a working script, but also teach me a trick or two:)
