I have jailbroken software 2.0.1 on my iPhone 3G and i have started to have problems with Installer 4.0.
When i open it, it asks whether i want to update. I press update and it says in a small blue box 'Error - bad URL'
I cannot get into any repositories for example i added Swirlyspace to get SwirlyMMS and it added fine. I press it (SwirlyMMS) and it comes up with 'Error - Unable to decode package more info at http://www.swirlyspace.com/forum'. I also get similar errors with every other package on the whole app.
I cannot go into any of the featured apps. I press one, and my iPhone returns to the home screen.
I would really like to be able to use some of these but i cannot. Any ideas from anyone? Cydia works fine, loving it!
