Apple iPhone 4 and bluetooth devices? o.O*

[Kuschel-Drow]

Well... just tried to connect my new iPhone 4 with my good old Nokia N97 to send me some stuff I wanted to keep, like contacts and stuff, so I wouldn't have to copy them manually.
I could easily interlink both devices (although I haven't found out how to send anything via bluetooth using the iPhone, seems that it only looks for devices and then gets stuck while never finding anything...) but each time I try to send something from my Nokia the connection is lost without even asking me if I wanted to receive data on my iPhone. And my Nokia phone just tells me that it was impossible to get a connection, while both devices are still interlinked...

I'm totally lost now, I don't have any clue how this is supposed to work. Even if the data I'm trying to send was incompatible to the iPhone, shouldn't it tell me so, instead of breaking up all connections? o.O

If anyone knows how bluetooth on the iPhone is supposed to work then please tell me. ^^
