Hi I have just upgrade from Android 1.5 to Android 2.1. I find that the new default Calendar app is not as good as the 1.5 one as entries cannot be edited. Is there a way I would install the 1.5 calendar app on my 2.1 phone. If so, how do I do this and where can I get the old app? If not, can anyone recommend a similar free Calendar app. Thank you.
