I am working on sip 3.0 plugin for Series60 SDK. I have read the following from the sip 3.0 downlod site at forum Nokia.
"SIP plug-in 3.0 is compatible with all Series 60 Developer Platform 2nd Edition SDKs that support Feature Pack 2. (Please note! Nokia SIP Plug-in 3.0 for Series 60 SDK does not currently support Nokia 6630.)"
Does sip 3.0 support 6680 (which is just released in the market.)?
