Currently i'm using SGP screen protector only so I'm not realy sure if you could put in your SGP Shield .
Without the shield its kinda very tight already once you put the Epikcase on.
I think I'm the first person who asked the case from AskarPerang, all along he was just selling Nokia cases only. Lucky he sells iPhone case too

.
I bought 2 cases from him, 1 clear & 1 black. I love the clear version alot.
I'll give Epikcase Review
iPhone Casing: Epikcase (for 3G/3Gs)
Price: RM 15( from AskarPerang)
Rating: 9.5/10
Pros:
1. Covers chrome bezel,
2. Same build as iSkin Solo/Fx
3. Thinner than iSkin Solo/Fx
3. Cheap
Cons:
1. Water look-alike sign on Apple Logo ( But it doesn't irritates me much)
Comments:
It is a great replacement for iSkin Solo/FX with a great price. It is unbelievably reasonable as it cover your whole iPhone including the volume button and sleep/wake button. It can be put into pocket easily and increases grip on your hand. Buyers will never regret buying one with such low price.
I actually bought similar cases or I should say same, from a seller here at GS at lower prices.
My query here is that in the pictures in the review posted, at the back of some of the casings, there is the Epik logo and in some there is none. Does that mean the latter is fake?
Could someone clarify on this? It would help the forummers who are interested in this casing.
