by using the apple leather/ silicone case, will the uncovered area got scratched (for jet black)? ive been using apple leather case for ip6s space grey, haven't got any scratch at all up till now.. but since the jet black can be easily scratched, should i be concern to this small opening?
pls refer attachment for apple leather case.

do u still hear the "hissing" sound while wearing a case?
apple case is a great case. not so bulky.
i can say its pretty slim compare to other case such as verus iron shield, but its not ultra slim.
i dont suggest u take other colour besides black if gonna go for apple leather case (trust me! ur gonna regret it!)
but if ur going for silicone case, any colour should be ok.

Leather case
+ original leather
+ the smell of real leather
+ premium feel
+ good quality and details.
+ inner microfiber cloth to protect the device from scratch
- button quite hard to press for the first time. it will gets better over time.
- quite slippery / less grip when holding
- darkening on the edges / black marks (if u chose other colour besides black)
- appearance of the leather will change over time as u use
- not easy to clean, need to polish or u need to find a leather expert to maintain the case.
- more expensive compare to the silicone case

Silicone case
+ very nice grip on the phone
+ idk how to say this but the silicone material seems quite different (in a good way), it is very good quality.
+ inner microfiber cloth to protect the device from scratch.
+ can be easily clean with water
+ less expensive compare to the leather case
- when u have a small area get torn, its quite easy for the torn area to make the rest of the silicone to tear apart.
but if u want an ultra slim case, a forumer suggest to take this case

**but pls be reminded that some user review said that the case might gonna leave some scuff marks on ur phone. the best solution to avoid this is to at least clean the phone and ur case once or twice a month.

anyways, if ur wondering how does the case look like after 1 year (now), pls check the attachment.
