You could find yourself in trouble with that listing.

It doesn't matter how many times you state damaged, as is, may only be fit for spares etc in the body of the listing the item specifics take precedent and you have listed as used not as for spares and repair.

Second problem you cannot post it in a pre paid satchel, you have to post it regular small parcel with a road only sticker on it and you should register it with extra cover so it is covered up to the total value with AP and had Paypal protection.

Mobile phones have to be posted road only in Australia and cannot be posted overseas by AP at all.
