How to upgrade from already jailbroken 4.3.1 3GS to ios 5?

[jazvdb]

So my current situation is that I already have my phone jailbroken but I wanna upgrade to ios 5...

I do not want to lose anything (i have stuff from dreamboard themes and other cydia stuff), is this possible or will I have to start from scratch?

Also, how will this affect the memory/ram of the iphone?
(Im averaging of 110 mb of available memory if im not using dreamboard)

thanks

As far as memory go I don't see it gittin any better with iOS 5 unless ya git the iPhone 4s.


As far as all ya dreamboard theme I would ssh them to your computer drag the whole dreamboard folder over to ya desktop. Updating from iOS 4 to iOS 5 you will have to do a full restore i suggest sync ya phone before to
