Yes the current MobileTerminal on Cydia doesn't work with iOS4 yet...Ok if you're asking why to change root read this http://justanotheriphoneblog.com/wordpress/iphone-tips/how-to-change-the-iphones-root-password
But I'm trying to, and downloaded mobile terminal and when I launch it, it appears for 2 seconds then just quits. I've reinstalled, rebooted phone, still does it.
So I thought I'd use my terminal on computer to connect to my iphone through wifi. They're both on my uni's wifi network. It said connection refused?
Should I use mywi to create a network and then once tethered try to connect?
login password: alpinessh root@<ipaddress>
type new password twicepasswd
You rock.What I did on Windows to change my root and mobile password.
1) In Cydia, install OpenSSH. Respring phone.
2) Google for PuTTY and install onto your computer.
3) Startup PuTTY. On main page, type in your IP address. Make sure "SSH" is dotted then click "Open."
4) If this is your first time, a window will appear saying something about saving authentication key. Just click on yes.
5) When you get to the screen that says "Login as:" type in: Root. Password: alpine.
6) Now, it should say your iphone name. Type in: passwd. Enter new password and repeat. Once done, just exit PuTTY.
7) Repeat step #3. This time "Login as:" Type: mobile. Follow rest of instructions.
8) If you don't want OpenSSH, go back into Cydia and remove it. Respring the phone.
