Just keep in mind, that opening it Yourself *and* leaving some traces about it may void Your guaranty on last repair done via insurance. You know, they may say that it's Your fault, cause You tried to modify something after.

Normally, I also like to do things like that myself, but if Your phone was repaired via semi-guaranty repair (insurance), I would go through complicated process of kicking their a.s.s to fix it properly.
