Can the snapture from cydia run on 3Gs OS3.0 ?

Mange to JB on 3gs 3.0.1 firmware,after launch cydia prompt out available upgrades file,should i update it or leave it alone?thx for helping

sucessfully JB my maxis 3GS, but Cydia somehow crashed at nite....with message-error datebase....

Now, i am stuck with my new iphone 3GS without Cydia...without SSH to rectify the faulty cydia...

tried searching online, and found that i can edit/sync cydia vide a software called CYDER, tried...but not working or i dont know how to use it 

So, now, i hv only 3 winterboard themes, Mxtube for my JB phone...

All i can do is wait....for the devteam to solve out the restoring/downgrading of 3GS, then only i can re-JB

that's fate after more than 1 month waiting to JB 3gs, thats what i got now  ...

wondering if any sifu know:-

1.  other then the boss pref/SSH install vide cydia, any other way i can install SSH for my iphone without Cydia/installer/Icy? (i myself doubt there is any, it is my stupidity not to install SSH as soon as i JB the device  )

2. any app in apple app store similar to SSH?
