How to delete/uninstall applications (works only on rooted phone)
to execute commands on phones you need adb installed
1) mount /system/app as read/write
adb remount
or
adb shell
mount -o rw,remount /system
2) remove the apk file
adb shell
rm -f /system/app/<apkname>.apk
3) uninstall the application
pm uninstall <package name>
google "barebones cyanogenMod Wiki" to find a chart showing the correlation between the <apkname>.apk and <package name>
wrong, u do not need adb installed, that is not ur only option and there are easier options, u can use 1clickroot with has its own adb interface and is scripted to provide u root access, then u can use a file explorer with mount/unmount capabilities to navigate to system/app/ and remove the apk's and odex files u wish to remove (such as the bloatware stated in the op)
u also left out that if he does use adb he would also have to remove any odex files that correlate to the apk he wishes to remove, unless there isnt one, or unless he has already rooted and has deodexed his system apps and framework
