first you both need to use ssh
i use winscp and iphone tunnel suite
when you nav to the folder right click and select properties and use 755.
this .deb file wasnt so great. it kept crashing. i ended up adding another repo and d/l'ing it directly and it now works. as for the repo, you're gonna have to do some searching cause i'm not going to name it in such a public forum. hint: part of it's name is listed within this thread :)
use google. it WILL help you out.
there are many good repo's available for cracked JB apps.

permissions make an app run. sometimes your app might just crash for no good reason. if it does go to it with iphone browser and right click the app folder and select "properties" once there you'll see the permissions screen. just enter "755" and your done.

you'll know when its ready!
the last thing dev team should be doing is giving out dates. cause as soon as that date comes near, people like you come along and start flipping out when its not ready.
