I've tryed to send the sample for the 5100 to a nokia 6220. Although the mobile received the configuration messages, nothing happened!
The same sample sent to the Motorola C350 works.
Do you have any succesfully tested sample on the 6220?
I am working in a Nokia 6220 and a 5100 both with a TCP/IP stack, and they both accept the above mentioned wbxml document. Even the T610 from Ericsson answered to ! and I suspect the P800 will also. The Motorola C350 however, I get no response from.
