I have a blackberry curve 8900 in brand new condition. It was purchased in April and had an invisible case on since day one. I didn't do a great job of putting it on but its on and protects the phone. I also have a silicone gel case and original box/accessories with the phone. You can take the invisible shield off and the phone will look brand new. I also have an extra invisible shield you can put on your self or have someone put on for you. I also purchased a 16GB microSDHC for the phone. I'm not so sure how much these sell for so lets just say 450 or trade for an iphone 3g or 3gs. I will however entertain your offers via pm.
