I installed it but when I press the icon to launch it IT KICKS ME OUT... Now what should I do? It seems I can't remove it from the springboard... neither by modifying it from CYDIA. iOS 4.1 - iPhone 4
How stupid was I? I managed to remove it... ;-) from Cydia (of course!). And here is the solution: remove it, then install the beta package from xSellize (X Apps) under the name of "MobileTerminal iOS4" (search it on Cydia). It seems that the iOS4 isn't supported from this local UIKit-based Terminal emulator in this article.
