[Zaktrain]

I haven't been able to find an answer on this anywhere so ill ask it here is the untrusted package safe?
I just got this phone and i don't want to turn it into a paperweight and help will be appreciated

You will probably have to give more information than that for anyone to help you - for starters;

1) what is the name of the untrusted package?
2) who is it from?
