I just tried to get my own app on my iPhone without a developer account. The following are steps I did:
I patched Xcode and my project (Currency.xcodeproj) with JailCoder
I want to build the project with "iOS device" in Xcode. But I got a error message like "no device found". So I ran it in the emulator and I got the currency.app-file in /Users/Dogan/Library/Developer/Xcode/DerivedData/Currency-gjxrulouxbmjslbzslsplyehgfgm/Build/Products/Debug-iphonesimulator
SSH to iPhone in /var/mobile/Applications
Creating a new folder named FADE9826-4878-4458-B5BE-90AD4EB60FDF (I have to take a valid UDID. Have I use to specific tools to create a UDID? I have the UDID from an other example). I also created a directory in this folder with the name "Documents".
chown -R mobile FADE9826-4878-4458-B5BE-90AD4EB60FDF
scp -r Currency.app root@IP-ADRESS-OF-IPHONE:/var/mobile/Applications/FADE9826-4878-4458-B5BE-90AD4EB60FDF/
Restarting Springboard in SSH with "killall SpringBoard"
I got the app, but it doesn't work. Every time on click, it crashes and kicks me to the home screen. Had I missed something?
