Hi, I purchased a knock-off aluminum bumper on eBay. I received it today and I have a few questions. Link: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=250786487361&ssPageName=STRK:MEWNX:IT The biggest problem is there's a gap on the left side of the case. Meaning the silver antenna is showing. I think it's bent a tiny bit. I contacted the seller and he's sending me a new piece. The first questions is about the signal loss. For others with the aluminum cases/bumpers, do you experience any issues with the bars and signal? I've had one bar all day in my house, yet I usually have 2-3. And I just made the first phone call and it took longer to initially connect. Lastly, the phone wiggles around in the bumper. The screws are as tight as possible, and I used the foam pads like I was supposed to. It's not going to fall out, but it moves around.. Is this just because of the first issue, because it's a knock-off, or both? Thanks!
