There was a post awhile back on a fix for this that works very well. Basically, you use a hairdryer to heat up the plastic bottom and then mold it upwards by applying some rubberbands around it from top to bottom. Do this with the cardboard iPhone like cutouts in the case to prevent it from collapsing. Then you stck it in the freezer for about 10 minutes. Wala. No more sagging. Basically it makes the bottom sort of bow upwards and when you put the iPhone in it no chrome shows at all. And the fix lasts. I did it to three of my rebels a few months ago and they are all still perfect. Try it out. Just don't get the plastic too hot cause it will melt. Heat it on low for like 30 seconds maybe only.
Good luck.
I called them when my White case started to Sag and they sent me a new one.
Well, i tried the blow dryer to freezer trick, and it worked. I can't say for how long, but it definitely fits better. I also e-mailed Switcheasy and i will let you know what they say
There is a new rebel now, or at least a new version of it called the Rebel Serpent, maybe the sag is fixed in that one. It's on their site www.switcheasy.com
I bought a rebel capsule for my iPhone last week and it does not sag. Before I had it on the phone, the flap was actually curved in slightly, but once it was on the phone it is flush across. Maybe they recently changed the design to fix this.
I'll post my own review about the Capsule Rebel Serpent once I get it, I'm looking forward for a non-sagging case, just like what applegurl and MikeyDg got (they're from youtube) unfortunately Carlos had bad luck on it.
