Is it possible to modify an iPhone 4s to fit an iPhone 5 case?

I bought an iPhone 4s and the person i bought it from gave me the case off his iphone 5. The case is nice but they don't make it for 4's. Would it be possible to modify the 4 to fit the 5 case? I understand the 5 is bigger, which is why i was thinking thin strips of electrical tape or rubber, to give it a firm fit in the 5 case, but if there are any other ways to go about it, please tell me.

its an actual Gucci case in case you were gunna say "just get a new case"

I don't think there's any way possible to definitely ensure that it's "modified" safely. I think you should just try your idea and see how it turns out.

The iPhone 5 isn't only larger, it is thinner as well which means the 4 is thicker than the case. I would check and see what cases Gucci has online for the phone and also check other countries because Gucci sells different products in different countries.

No.

The only way you are going to make this happen is to get a new case.

The iPhone 5 is both thinner and LONGER so it's just going to fall off. And if it's a true Gucci case, then trying to fix your phone to fit the case is only going to damage the case itself AND the phone which would defeat the purpose of even having the case at all.

Sorry, but the only answer here is to get another case. I'd suggest looking on eBay
