hmm... Im using the same verison of iphodroid but am on 4.0 firmware, I presume you were able to successfully boot into android before you renamed the files and placed the iphone ones in the same folder? and you defintely copied both files from with the rar successfully? also did you move them via ftp or with cable (if ftp I would suggest try moving them using iphonebrowser on a cable).
I had this problem also, best thing is to go to boot screen and go to the bottom right hand side and uninstall android. Then go to the iphone os connect with wincp or filezilla and remove the 2 files then start again. I had the same issues yesterday!
I transferred the files this time with filezilla, and now it works. My PS3 starts up with the 2 extra maps installed. I've only one small question, is it normal that when booting android and booting ps3, my iphone get stuck at: "libertas_sido mmc0:0001:1: firmware: requesting sd886_helper.bin"
