3.0 Already JB how to upgrade to 3.1..


Standard Member
Hope somebody can help,been looking at various threads but cannot seem to find a stright answer.
IPhone 3gs 3.0 f/ware allready JB with purplrain with no problems.

Since the orginal jb i have intsalled many apps and personal information and files that i just cannot afford to lose, therefore if i update to 3.1.2 then run Blackrain will i lose all apps , settings , info etc.

Also what is the best way e.g

Run update through Itunes - restore - blackrain OR
Update - blackrain - restore, mANY THANKS IN ADVANCE.

I updated then used Blackrain.

When I reinstalled Bosspapers, it started working as before.
Also on reinstalling Yourtube, my downloads were still there. Same with Lock Info etc.

Some folk like to restore as a new phone then JB for a clear out. I prefer to do it the other way.

Did a back up, updated my 3.0 JB'd 3GS to 3.1.2, ran Blackrain, did a sync then reinstalled my Cydia apps. (I wrote a list of what I previously had).
