trying right now your link... damn... My modem version is 04.05.04G maybe I do have an old kiPhone...
Ok, i downloaded a new kiphone and once it ran, the iphone had a message for me: repair needed. this phone cannot receive/make calls. am I doomed???
10 minutes later - IT WORKS!!! I just needed a new kiPhone installed!!! YES! Thank you Poseidon!
What I did was installed new kiPhone, iErase and downgraded and debuged. Then restored in iTunes, then I got that message about repair needed. Indeed, all the info about the bluetooth/modem etc was erased! Then I restored again in iTUnes, and then jailbroke by ziPhone. That's all folks!
