Don't know where else to post this so I posted it here.
My phone chirped in the middle of the night, I checked the phone and i had received an email from my dad. I didn't read the email (it remained marked as unread), and instead went back to sleep.
I woke up and wanted to read it, but it had vanished from my inbox (and i checked the trash folders and ever other folder as well). I spoke to him this morning and he confirmed that he did send me an email.
And looking at my folderlist, theres a new folder i've never seen before "trashFolder: Deleted Messages". WTF is going on?
