[Q] Best way to do apps to sd without losing anything?

---

Hi guys, I used to mod my old G1 all the time, never had a need to on the Desire until now, I'm running out of room every day!

I have a rooted Desire with rooted stock ROM, I'm wanting to do apps2sd old style (not the google way!)
What's the best way to go about this?
I have a 16Gb card in the phone but I don't want to lose any apps or settings I already have installed (I have backed my SD card up to my PC so I can put the 3 partitions on)
Once I have set the 3 partitions, what do I install to enable Apps2SD and where from?

any help appreciated

Anyone?

Maff, from my Tab

I'm in the same boat, in addition to what "mmace" has asked, is it actually possible to use app2sd on stock roms once rooted, and also, for those that are using apps2sd, is it possible to unmount your card and use it as a storage device on your pc, or will that screw everything up...
