Erasing all SMSes on 3310/3315

[Brdo]

How can i erase all SMSes at once on 3310/3315 (5.79)? I've read on this forum it can be done, but it didn't say how (and i didn't find this option either).

Thx,
MrBrdo

Well i have been using the v5.57! So if there's a huge diff, i apologise! But in messages menu (2-11-1) I can erase all read msgs! i'm assuming this is what you meant! If you want to erase ALL msg's as inone's u haven't read... as far as I know that can't be done!
