Sadly, I can't find the page where the 3 options are available - when those were there, I remember seeing some priority to the 100 and 40 orders over the 0 orders.

Of course, you may not trust my memory (and you would be wise not to). Evidence rules.

Now, we can compare notes if you like - if you have a 100 or 40 preorder, have you got a sequence number? I've got a 0 order which doesn't.

The above makes sense as this: http://web.archive.org/web/201306091...ders/new?order[bundle_id]=2 said that you got a "Limited ed. Jolla preorder number" (whatever that means) and this: http://web.archive.org/web/201307071...ders/new?order[bundle_id]=4 doesn't include any preorder number or anything.
