Newest RedSnow release. Will it unlock 4.2.1

[jerrykb]

My phone is JB with greenpoision but was wondering if i were to restore it to stock 4.2.1 simce I have SHSH blogs fom TU, if i could then JB It with redsnow then use ultrasnow to UNLOCK it, woul that work? The big problem for me is that i have 05.15.04 firmware.

Thanks for any assistance.

.....No. Once you update your baseband you are unable to downgrade back down again at this time, regardless of which tool you use to jailbreak. Your best bet is to buy a Gevey.

Yes and almost . Baseband 5.14.04 can not be unlocked. The only unlock option is the iPad 6.15.0 baseband. After an unlockable baseband is installed, ultrasnow will unlock it. Use redsnow 0.9.6rc18 to jailbreak and install the iPad BB.

But you must know that when you insall the iPAD BB your GPS WILL BREAK. YOU WILL NOT BE ABLE TO USE IT. Just thought id tell you incase you didn't know.
