I put a Martin Fields screen protector I got from AbsolutelyU.com. They don't carry one specifically for the 6800, so I had ordered one for the T-Mobile Wing since the screen size is identical. My screen looks great and is protected. They sent me some business cards with the coupon code "cardme" for 10% off if anyone wants to use the code.
I also got a Kingston 2GB micro SD (with SD adapter) for about $8 after rebate from buy.com. Works great in my 6800.
