Ero-Fan: I theorize that ichigo is technically dead at this point, but still able to possess his body. We see him in his real body just prior to leaving for SS, but after the training took place.

darkmetal505: Kon is not in ichigo's body.

Both of you check episode 20 to see what i mean. Urahara uses his cane on ichigo just before they leave, then then they pretty much just leave his body idly lying on the floor there.
