Luv the Case-Mate Signature. Considering its use-in case style, it protects the iPhone very well. Just dropped it for the first time today on a Toys-R-Us tiled floor. Yikes! It landed right on the iPhone's screen and skidded across the floor. To my surprise, not a scratch, ding or nick on the iPhone screen or body.

Case-mate also carries a flip-case as well. Might grab that down the line.

Be warned.... The belt clip on the Signature iPhone Holster is very poorly designed and not very strong.

This was by far the nicest, most well designed case when I bought my iPhone, and I got it straight away. Immediately though I saw that the clip was a pain to use because the phone is so slim, and fits nicely into my pocket.

Because of that, I went a couple weeks without the case, and then dropped in on a Home Depot concrete floor. Despite the PC World thrashing tests that showed it nearly impossible to scratch the screen, I did manage to get two small dings on the screen. Ouch!

So the case has been on since, without the belt clip. I am sure if this case at been on the phone when it hit the Home Depot floor, it would not have scratched because the screen remains recessed with the case on. Silly me.

Bottom line is I highly recommend this case because it doesn't get in the way (without the clip). And it's classy. Too bad it took that fall for me to realize it though. Not so shiny anymore.

Overall - nice case - BUT one downside of the case is that the bottom inside of the case is rough and when you take the phone in and out of the case (e.g. to put the phone in the syncing dock) the roughness of the case scratches the bottom shiny silver metal on the case.

Purchased the combination leather case and leather holster. The holster is much superior to the screw on clip that comes with the case. Agree with much of the review but would add one important note of caution. When the iPhone is in the case and the phone is moved to your ear for a call, the iPhone screen will not always go blank. In my case, the keypad was still active and movement against my ear or face triggered keypad tones during a couple of calls.

This is my second case. I tried the Speck for a while, but this is the style and size I prefer. I use the case in conjunction with the holster. It is a good combination.

The holster's clip is large enough to accommodate the instructor's belt I wear and the internal suede lining keeps the iPhone secure on my hip.

The included screen protection sheet installed easily and has done its job.

All in all, the Case-Mate case and holster is a good set-up.

Jose, Steve: Thanks for the comments, although I should add that after using the case off and on for about a month, I didn't experience either issue. The iPhone's proximity sensor worked well in the Signature for me, and even though I inserted and removed the iPhone many, many times, the case never left a mark on the phone.

I have tried a bunch of cases and the Case Mate outclasses all of them I have tried and seen. It took a little getting used to. You have to really screw on the clip to the case so that you can take advantage of the ratchet mechanism. Also, the good news is that the clip holds the phone very securely. The bad news is that the clip hold the phone very securely. It takes a good push to release the phone. I have had no problems using the iPHone for a month now. I bought the holster for those times I feel like I need more protection. I haven't felt that need yet because the case is so light, I can wear it even with just my workout shorts. The holster is a bit heavier.

The clip popped off (out) of the leather case after about 3 weeks when I was getting into a car. It was glued onto the leather (and not very well) rather than being part of the plastic body underneath. The screw on portion of the clip only gives an illusion of security. I cannot imagine why they thought gluing plastic to leather on a stress point was a good idea.

I thought this case was neat at first, but now I am just disappointed.

After my earlier positive comment, yesterday I experienced the same problem with the clip popping off the case as Bic above. I called the company and they said I had to return it to the ATT store where I bought it. I told them I thought it was a serious design flaw to have a plastic clip glued to the leather and they said they have been hearing this is a problem. I am going to replace it, but it is clearly a major problem and will not last. If it is not fixed, and if they don't retrofit or exchange older buyers with a new design, that would be a big problem for me and any consumer. We should all stay posted because this could be a consumer class action issue if not corrected.

I hate this case and my iPhone has sustained major cosmetic damage as a result. It is definitely one of the prettiest cases out there, but the desirability stops there.
I have had two of these, both the belt clips busted, and the uprights, (besides always plucking my upper ear, bend and the stays within the leather break.) I haven't had any luck getting in touch with case-mate, another stinging point. Don't buy this unless you just want an expensive cosmetic only case for 1 day.

I was exteremly disappointed with this case. I have been through two of them so far, and on both cases the little screw-in hole for the belt clip has ripped out within a few days.

It's also annoying that the case prevents the iPhone from sitting in its cradle. In the process of removing the iphone from the case to sit in the cradle on my desk, the top of the case got bent up after a few days so it doesn't sit flush with the phone any more.

Maybe I'm just rough on my cases, but this one just doesn't seem to cut it.

This product is dissapointing. I am the third person I know personnally to have the screw on the back just fall off. What bites for me is that my iPhone now has a dent in the top of it, and Case-Mate will not warranty there product over 30 days. I'm at like 34 days. Thanks Case-Mate.

I want to thank everyone for their comments here, especially those with feedback about the belt clip. As I noted in the review, I didn't like the belt clip's design; however, it didn't break off as it apparently has for some people over time. It's good to get this long-term feedback about the clip breaking, which seems to be a fairly common issue.

KeithAW: Keep contacting Case-Mate... if enough customers hit them with this design flaw issue, they'll eventually yield (even if only to continue replacing the product until the design is modified).

Haven't gotten my phone yet (supposed to be today, but no luck), but even with the critiques, I haven't seen any other offerings that I would go with.

I've used this case for two days and it's already scratched and scuffed the chrome on my iPhone. Definitely wouldn't reccomend it...

I'm on my 3rd case within 3 months (roughly, a case month) due to the belt clip breaking each time, and I'm going to replace it today (Hello #4). While it's cool and sleek, I think it has a poor design; instead of having the screw anchored to a metal or plastic peice, it is basically glued to a cardboard backing. Also, the swivel on each case has a different degree of tightness. Fortunately, Case+Mates has given it a lifetime guarantee, so AT&T keeps replacing them free of charge. But since this is the only one I like, back to AT&T I go.
