I unlocked my 903sh yesterday. And I found 2 files in my mini SD card. These files are "basket_case.dcf" & "eureekaseven.dcf" They both are located in the video folder and show "cannot play".

Are these 2 files associate with the unlocking stuff? Or they might be some files that the store salesman saved in the card and forgot to delete them?

Can anyone tell me if it is OK to delete them? Thank you!
