I was worried for nothing. The SE is already in the post. My son is happy about that :-) Thx Digitec!

This is really questionable, but probably something Apple wants and triggers through artificial scarcity. I placed an order as soon as the pre-order was possible, but have now cancelled it. You can order the iPhone SE directly from Apple today and it will be delivered on Monday. I would have preferred to buy it from Digitec, but waiting more than a month is a bit too long. I like Apple devices, but find the company very unappealing. Repairs, availability of devices and the out of touch Apple stores etc. is just frustrating.

A pre-order is never a guarantee that you will receive the product (See PS5 release).

I think that the demand for this device is certainly high and digitec only has a limited number of the product available.

It's a shame, but I don't think there's much you can do about it. Except don't lose hope, of course ;-)
