TasKiller Free for Android

[asforel]

A must have for G1 users… I can backup my apps, install apps, zip or unzip. it even has the abilty to move or copy files or send. I luv the list view but has more options. When i backup more apps due to the low internal memory on the G1 i can see which ones are out of date, which are colored in red. select those apps to backup again… boom!! ZaP! POW! your new version is backed up.
