I mistakenly said yes to importing all my addresses from my old phone to the Aria. The ATT person put them all on my SIM! Now they are uneditable and a pain to manage. Is there a way to delete all the contacts on the SIM all at once. I'm not looking forward to an individual delete process.

Ok go into People>Menu>View>SIM Only.

The from within People, select Menu>Delete and check the boxes next to the ones that you want to delete from your SIM, then touch Done.

Nicely done. Thank you!

Thanks for the post...it answered my problem as well !!

I went thru this, and it says its deleting them, but they are still there. ARG! What to do????
