SE44 contact lists

[brokenshadows]

My company is donating several SE44's that we were using as spares to the local womens shelter. I've gone in and reset the phones to the factory default using ##786, cleared all saved txt messages and voicemail notifications etc. but the one thing I can't seem to do is delete all contacts at once. I can delete them individualy, but some of these phones probably have close to 100 contacts in them (I think company CEO's view contact lists like pr0n stars view the size of their...well, you get the drift...the bigger the better ). I do not have a data cable for these phones anymore...so I can't use software to edit the contact list like I do with the KX12's we use now.

After that long winded intro, here's my question... Is there a way to delete all the contacts at once?

Thanks,
J
