Thread: Deleting ALL smses

Hi everyone,
I have loads of smses in my HTC Diamond2 (which runs on WM6.5 platform), and my phone has been freezing up. So I tried to delete all smses but I couldn't find the option. I somehow managed to clear the main inbox but now all the smses are in the "deleted items" part of my phone inbox and that's where I'm stuck. Can I delete them all the smses at one go? if yes, how do I do that?

Thank you so much!
