Custom SMS MTM

[murthy.pramod]

I have a SMS application which is very similar to native SMS application.It is able to recieve notificaton of New Message, view messages in the inbox,drafts & sent Items. I also have my own editor to type messages.
I want to integrate this app with native app with an option of selecting either the native or my sms application while viewing and composing a message. I want to use MTM to customize menu for the same. I have gone through similarn Text MTM Example for email in S60 3rd Edition. But it differs a lot for SMS ?

the answers so far on forums have been either "not possible", or then only little better "looks like possible somehow but nobody who knows is ready to tell".

posting here hoping for a much better answer

I would start by evaluating whether you could get enough functionalities by using bio-messaging, instead of making new MTM. Would propably be a lot easier to make.
