Developing ondevice for Xcode 3.2.3 (iOS 4.0)?
Does anyone know how to install and debug apps on iOS 4.0 (w/o paying $99)? This guide make it possible to install apps on iOS 4.0, but unfortunately the debugger doesn't attach to the process (= not working). Josso 09:28, 1 July 2010 (UTC)
use gdb via ssh for debugging (it's in Cydia)

I added a bit about how you can find prepatched versions of installd by adding some alternative repositories to cydia. Unfortunately, said repos tend to have pirated apps, so I linked to a google search, rather than any particular site. Using cydia to overwrite installd is far easier than trying to build a patched version yourself.
Also, at some point, xcode updated info.plist, and it now has three places where you have to replace XCiPhoneOSCodeSignContext, rather than the previous two. Fake-Name 05:13, 20 September 2010 (UTC)
