PROBLEMS IN J2ME IN RECEIVING SIP MESSAGES IN NOKIA E60

Question

Hello guys!
I'm currently developing an instant messaging for sip messages in the NOKIA E60 platform.
Registration process to the proxy functions properly, sending of messages to target URI functions properly, however, when a softphone send a sip mesage to the proxy-routing to my application. My application doesn't receive anything. I used the ethereal to see incoming frames in the proxy and i found out that Nokia E60 send a "bad media type mesasge" as a reply to the message. Any feedback in this matter ? My code is written below:

Hey!
1. Nokia hides some folders containing system stuff, so that you don't accidentally delete something and mess things up. The computer sees more of them and can count them in, so...
2. It happens because your wallpapers are stored on the Mass storage/ Memory Card drive... And if you connect your phone to the computer, it won't be able to read any files on E/F drives as the computer acceses them.
3. They are! You just have to scroll down the list that pops up when you click on the widget
4. Try this one: to snooze an alarm, turn the phone on the other side, so that the scrren faces the table- it will shut up!
5. Nope, they're usable straight away
6. Don't really see what you mean... You want the messaging app shortcut to open up with folders (outbox, inbox, stuff like that?) I'm afraid it's not possible You'll have to access them via the options menu
