deleting messages

I have a question for the crack berry nation. different OS versions delete the messages in each folder. My BOLD 9000 and now my Torch seem to delete everything in every message folder including sms messages. some OS versions only delete the folder you choose and leave the rest alone. is ther a way to enable the feature to only delete the folder you are in? I like that better. seems like with different builds this feature is sometimes there an sometimes not. why does this change?
I am currently running the 6.0.534 on my Torch. and it deletes everything. the 448 only deleted the folder I was in . I wish this would stay part of the OS. I don't always want to delete my sms conversations , only my emails. annoying!! is there a fix or are we just stuck with it? thanks.

I don't know if this will work for you, but on OS 5, I can go Messages>Options>Inbox Settings and uncheck Other Message Types/SMS and MMS. That way only my emails go to my message folder.

I think you solved the problem . i don't have an sms to test it with but looking at that folder makes sense the other message types was checked off, that would dlete tose along with. how does that get checked? I have never been in that folder before? I will now!! thanks! crack berry again to the rescue!
