Since the Z1s is an exclusive phone for T Mobile in the US, I suspect that accessories like cases and screen protectors will be scarce. Consequently many "eyes" will help us all keep informed on what is available and may come available. Let's share what we find and/or use. I'll start. When I got my Z1s I wanted something immediately so for a case I selected the Tech21 Tactical case. Here is the link: Sony Xperia Z1S Tech 21 Impact Tactical Shell - Black | T-Mobile This case is OK but has one major "flaw"......the magnetic connector is covered so you have to open the USB port to charge the phone. It doesn't add much to the dimensions or weight of the phone, seems well built and addresses the slippery feel of the phone. If it had a magnetic cutout I think my search might be over, but.... TMo had only one screen protector available and that is what I'm using. What can I say, it's a screen protector and has the appropriate cutouts for the Z1s' sensors. Also feels OK. I think I'm satisfied with it for now. I've also paired my Z1s with a Bose Mini Soundlink speaker via bluetooth. Paired fine, working fine. No complaints. And what about you?
