I have a problem and I need your help.

I dropped my iPhone 5 today. My screen broke. I've had iPhones for 4 years and I've never damaged them. It's with me when I snowboard, when I skydive, when I paintball. Shit, its been in my ACU's when we're practicing hand to hand combat. Did it ever break then? No, not a scratch. I dropped it 3 feet on to the parking lot and bam, spiderwebs.

Anyways, enough of that. The real question here is should I replace the screen or wait until the new one comes out and just trade it in then? Do both? Would it be worth the $150 replacement charge if I'm just going to sell it? And then is there anyway to get it replaced by Apple for cheaper?

Any input is much appreciated.
