MobileTerminal update is available in Cydia, it finally brings compatibility with iOS 5.1.1

  MobileTerminal is a very old application launched by saurik for all those who wanted to use command lines to control iOS or to learn more about it. Unfortunately, the application was not compatible with iOS 5 until today, but saurik solved these problems and version 364.3-12 of MobileTerminal should work without problems on the new iOS 5.1.1. With the help of this application you can install .deb files, you can change the password for SSH, you can find out information about iOS running in terminals, plus much more.

  MobileTerminal is available for free in Cydia in saurik's repo and works on any iDevices.
