Turns out that Samsung x640 don’t use the defaut settings to connect to the internet for java applications. And the way the Samsung said this was by simply freezing when it asked “Want to send HTTP information?”
This is changed in: Menu -> Fun box -> JAVA world -> Internet Settings and here entering the settings that your service provider gives you.
Doing so made me get past this screen.
(Just to bad I still can’t get it working 🙁 )
