I was able to upgrade my 3.0 3gs iphone to 3.1 cf in windows with the iPhone2,1_3.1_7C144_Custom_Restore trick. after getting everything running again and getting txt messaging, i realized that I was unable to change the pineapple on the boot screen.

usually you can do this through a mac by using the ultrasnow tool, but since im on a pc, i have no way to do so.

can anyone give me pointers on how to change the boot screen? i've already tried LogoMe, but it only works up to firmware 2.2 or so
