Copp, please remember the late payments that occured BEFORE you filed BK are still going to count against you....Any late payments AFTER the filing date will be removed....As noted by the other responder to your post, please make sure all of your accounts that were IIB say in the status "Included in Bankruptcy"...If they say something other than "IIB" than dispute it...some may say "Pays As Agreed/IIB, 30 late/IIB, Charge off/IIB"... Long as it sayd "IIB" you are good....
I had the same experience when my BK was discharged in Jan 2007....I still show lates that occured before I filed....But once I updated all accounts to say "IIB" my score increased significantly....
