Question about putting apk's back and theming

[BhamItGeek]

I dont want to turn aroudn and buy better cut.I have rooted and am running bb7.6 I want to start playing with the app icons and not how to go find the app apk...and move it to the sdcard and then to the computer and change to zip to explore the file. What I am not sure is putting the app back on the phone. I have read...or think I rememeber reading that you can't just go and put the apk back in its spot overwriting it. for example the phone icon... what would I need to do to put the apk back and getting it to work? I also would like to know how to remove the clock all together in the status bar.

once your done making your changes to the file. make it a .apk file again. open terminal emulator and use this code

su
mount -o remount,rw -t yaffs2 /dev/block/mtdblock4 /system 
busybox cp -R /sdcard/theapkyouchanged.apk /system/app 
mount -o ro,remount -t yaffs2 /dev/block/mtdblock4 /system
sync
reboot

if you do this with a market app, it will work but you wont get update notifactations for it
