I think this is the answer to the post I did yesterday. It is my finding too that HTC Scenes - once altered can only be saved in a new name. I did not find a way to delete or edit these scenes, to remove some widgets in those scenes.
I wanted to do the edit or deletion purely to make the calendar, GMAIL etc inaccessible if I lose the phone and block someone finding the phone to view them by changing the scene to HTC WOrk or Travel for example (in these scenes, GMAIL and calendar are getting displayed).
The App Locks are not giving opportunity to password protect those scenes. The locks (password protection) applied on the GMAiL/Calendar through App Lock Apps are not working (at least the first time one goes into those home screens after the change of the scene). I tried at least 3 app lock applications with the same result.
The above is true also in respect of Call History and People. Though app locks work on Call History and People when accessed individually, if they are accessed through Phone, they are coming up for display (I do not intend to block the phone also to address the issue).
If my above observation is correct, HTC left a hole for a back door entry to some of the apps I mentioned above (GMAIL, Calendar, Call History and People).
Appreciate if someone who has found a solution or an app to address the above can respond (e.g. an App or method that can lock the HTC Scenes or an app that permits deletion or changes to the HTC Scenes, without of course screwing the phone functioning).
My observations are in respect of Evo 4G (Sprint).
