Yes, just install Avast! Mobile Security, go to where it says Anti-Theft, proceed as told and you will have Avast!'s Anti-Theft app, and then you can uninstall Avast! Mobile Security and keep AT, which is just like TA, or even better
ok thanks, that answers my next question "why is there no anti-theft in the market?"
it's always hard to change a system you are used to.
---------------------------------
EDIT
I just installed the anti-theft software (and was told to uninstall theft aware, because they interfere each other). It looks a lot like TA but not bad though. And I had do uninstall the avast mobile security because it break down 3 time in 5 minutes ...
two hints for the developers:
1. the custom lock textlimit is really short
2. after "calling" the anti-theft Code you have to type in the code again, I don't think that double checking is necessary at this point.
Tomorrow I will check all the features with SMS commands.
