A quick search gave me no answer to this topic, although I would assume it's a known issue.

Anyhow, some 7650 apps do not work on the 3650 - my app included. It even does not work on the updated software I got on my 7650 after having it on service the other day.

"application may not me compatible with phone. quit installation?"

So what is the clue ?

What is the difference? what will I have to do, to get my series60 app to work on a series60 phone - a new one that is!
