I have the same problem with our internal application. I noticed that when we moved from ad-hoc, where the application was just installed on the spot, for the native application, the application is installed in the "installation ..." space, and then it actually takes up the next available space for the bridgehead (so - Apple copies the package from some temporary spot, it either does not delete the old package, or the springboard does not clear the icon).
SOOOO .... I just went and edited my manifest. I noticed that the Bundle ID does not exactly match the package ID in the application (because I changed it when I switched from AdHoc to In-House, for example com.mycompany.myapp, to com.mycompany.myapp.enterprise). After the package identifier matches exaccty, the application actually installs exactly in place (without the application icon next to the "install ..." icon when copying it - or something else). 8 ^)
Let me know if this works for you!
