2.1 I only removed the apps I don't use, One can add apps to the script if they like. more work is required for 2.1 "more typing required sorry" BTE free isn't available for 2.1 so use ConnectBot or another terminal.
First create a directory on your sdcard call it sprint_2.1 you can do this via plunging phone to pc and mounting it.
Code:
#!/system/bin/sh
# This Backs up your apps.
cat /system/app/AmazonMp3.apk > /sdcard/sprint_2.1/AmazonMp3.apk
cat /system/app/BejeweledDemo.apk > /sdcard/sprint_2.1/BejeweledDemo.apk
cat /system/app/FileViewer.apk > /sdcard/sprint_2.1/FileViewer.apk
cat /system/app/FileViewer.odex > /sdcard/sprint_2.1/FileViewer.odex
cat /system/app/im.apk > /sdcard/sprint_2.1/im.apk
cat /system/app/MoxierMail.apk > /sdcard/sprint_2.1/MoxierMail.apk
cat /system/app/nascar09-prod-release.apk > /sdcard/sprint_2.1/nascar09-prod-release.apk
cat /system/app/nfl-prod-release.apk > /sdcard/sprint_2.1/nfl-prod-release.apk
cat /system/app/SprintTV_MR2_Samsung_Moment_GM_Final_1.0.4.29-112596.apk > /sdcard/sprint_2.1/SprintTV_MR2_Samsung_Moment_GM_Final_1.0.4.29-112596.apk
cat /system/app/SprintTVWidget.apk > /sdcard/sprint_2.1/SprintTVWidget.apk
cat /system/app/Term.apk > /sdcard/sprint_2.1/Term.apk
cat /system/app/Term.odex > /sdcard/sprint_2.1/Term.odex
cat /system/app/Weather2-16.apk > /sdcard/sprint_2.1/Weather2-16.apk

Same know issues as 1.5, also don't run the app twice, unless you # the already backup up or removed apps.
If one runs the script twice without # out the line of code that backed up the app the app will be deleted from back up and lost.
What does that mean, lets say one backs up AmazonMp3.apk, if this same line of code is allowed to run again cat /system/app/AmazonMp3.apk > /sdcard/sprint_2.1/AmazonMp3.apk this will delete AmazonMp3.apk and replace it with a fake file, unless of course AmazonMp3.apk wasn't remove from system in that case AmazonMp3.apk will just replace AmazonMp3.apk.
