I wanted to make a list with Files that can be deleted without causing problems.
To delete any of this Files you need root + some sort of Root Explorer or Root Manager
I tested this with both of Leshaks ways of gaining root and used Root Explorer to delete the files.
The Direction where they can be found is /system/app
First off all the Standard Apps:
Aldiko eBook -> aldiko-standard-220.127.116.11....apk
Allshare -> Dlna
BuddiesNow -> Buddiesnow.apk
Clock -> clockpackage.apk
bookstore - bookstore.apk
Daily Briefing -> Infoalarm.apk
Layer -> Layer-samsung.apk
Memo -> Memo.apk
Mini Diary -> MiniDiary.apk
Myfiles -> Myfiles.apk
Messages -> MMS.apk
Navigation -> Navigation.apk
SozialHub -> undifinedInbox.apk
uTalk -> clientUTalk-03062010.apk
Writeandgo -> Writeandgo.apk
pre installed Tw Wallpapers:
I also tried to delete the Touchwiz Launcher and Replace it with the Launcher Pro Beta and it kinda worked. But there was a bugreport that said
"android.process.acore has stopped unexpectedly. Please try again. - Force close"
