MobileTerminal

[PHXred]

I am brand new to this, have been doing a lot of readig today on this forum and internet. This is my first time I jailbreaked my iPhone 3g 4.0.1 using Redsn0w. Worked great, thanks for all the info/help. One question, I know mobileterminal doesn't currently behave with os4, tried no luck, and I saw another forum mentioned google .zip file somehwere on here. I have yet to donwload on Cydia, is there another way to change my passwords to protect the phone? What damage can be done right now? Paranaoid just don't understand where to go from here since I can't run Terminal. Thank you for any help or threads.
