The usb port isn't really a DIY repair unless you have special tools and some skills with desoldering/soldering small, heat-sensitive components on electronic circuitboards.

I've seen too many broken usb ports! They get mangled from inserting the charger or other cables into the port at an angle and then using too much force. The port is very, very difficult to replace unless you have the talent/skill to solder really tiny connectors in a tight location. There are 5 tiny pins on the back of the port that are soldered to the main board that (for me) is impossible to to get at without possibly overheating something else on the board. To send it out will cost anywhere from $50-75 from what I've researched. That's why it's important to check the port before purchasing. If you cannot plug it in, at least look really close and make sure you see the 5 gold pins intact.
As far as replacing other items (lcd, faceplates, etc.) just Google what you want to do, or ask on this forum and people will lead you in the right direction. Or better yet, use the search function.
Picked it up last night. Its in amazing cosmetic condition with minor scrapes here and there. Talked to the guy for about 15 min or so. Said he just didnt like the blackberry and switched to Iphone. Ran the phone through the test mode and everything checked out. Got home and was even happier after I started playing with it. I cant wait to head over to the AT&T store this weekend to set up my data plan.
I checked the back of the phone under the battery and there were no red marks to indicate water damage. However when I pulled the battery to insert my memory card I looked on the bottom of the battery and the sticker shows the red Xs but its still slightly pink. The guy had said he had never gotten it wet and as i said EVERYTHING is working fine, is there anything I should know? Is this normal? I looked around in other threads and people stated that your OK as long as you can see the Xs individually.
I will post pictures when I get home. Not like anybody cares but I feel like I got a sweet score. Now lets hope I dont eat my words. I really appreciate everyone's advice
