If you're going with the glass screen protector route, I'd go with the BodyGuardz Pure. It's a little more expensive than the Glas.tr but its worth it. Supposedly it's slimmer than the Glas.tr. I have it on mines. It's slim but I don't know how slim the Glas.tr is. But what I like is the lifetime replacement plan. SGP has a replacement plan but only lasts like a month after you purchased the screen protector. Also it's $15 and you need to send in the screen protector first. With Pure, you can get it replaced whenever you need it. It's $12 (includes shipping) for a replacement. Also they send you the replacement first and then you send back the damaged screen protector. The price is a bit steep but if you don't have AppleCare and wanna keep your iPhone in pristine condition, I'd go with the Pure
