First off please forgive my ignorance if this has already been covered, I've been following most threads for the last few days and still have no clear answer. If a answer already exist please point me in the right direction (link maybe ) I'm wanting to update my 5.14 bb to the new unlockable 6.15, BUT want to keep my untethered green poison 4.1 jail break. A few videos I've watched seem to suggest it can be done using a mac and pwnage tool, but I do not have immediate access to a mac. I've downloaded the ipad 3.2.2 FW (which includes bb 6.15?) onto my PC from the link on the dev blog, which I assume needs to be jailbroken via redsnow inorder to install ultrasnow via Cydia? I'm confused how 4.2 fits into the equation. Whats the point of restoring to 4.2 if I plan to use ipad 3.2.2 FW. Lastly, I want to give a big thanks to the dev team for providing an unlock! For those of you complaining, go write your own software. I've been waiting nearly a month to use my phone and I can finally see light at the end of the tunnel!
