I've seen several SonyEricsson devices use this header, including the T68i. The Connection header appears to be using Token-Text to indicate that it is requesting an Encoding-Version upgrade. The Encoding-Version follows field appears as normal. I don't see this as breaking the ESP spec (see below), rather another example of the many manufacturer dependent interpretations of the stack spec.There is an correct "Encoding-Version: 1.3" header, but before there is an IMHO erroneous "Connection: Encoding-Version".
Connection header (0x09) is not marked as deprecated in last WSP
document, and I don't see anything that may confuse this processing - Encoding-Version is 0x43, not even similar to 0x09.
From the WSP specs -
"8.4.2.16 Connection field
The following rules are used to encode connection values.
Connection-value = (Close | Token-text) Close = <Octet 128>"
