Hey guys, I got the iPhone 3Gs when it came out, but I only got around to jailbreaking it yesterday. The phone now has wealth of possibilities, and I have already installed a bunch of things. Now that the initial excitement has settled, I am concerned about things like the fact that anyone can login to my phone using the root password if I am on a public WiFi network. I wanted to just use passwd and change it from the mobile terminal, but I thought I would ask a couple questions first. 1. Is there a password that allows the default user "mobile" to login that I might need to change too? Or is this user just an artifact of the MobileTerminal app I happen to be using? 2. Will I foobar the phone if I change the root password, or does everything play nicely? I assume passwd will make the change? Along another line of thought, I was also a little curious about iPhone backups. If I have an issue with my phone and do a restore through iTunes, will it also restore the jailbroken stuff? Or is there another way to get a real backup of my phone's current state? Thanks in advance everyone!
