    When I Build & Go from XCode and load an app to the device it works fine repeatedly until I change some source; then I get the E8000001 Verification Error bit when I try to reload. However, if I delete the app from hardware it'll reload again fine. Is this normal? or should I be able to reload (even after recompile) w/o any issues? If this is not normal, any ideas on what might be going on?

    I'm using a first gen iPhone with OS 2.0.2. TIA.

    Same sort of thing happened to me. Originally was working fine without this issue but at some point, perhaps maybe inadvertently interrupting an install of the app to the phone, but from that point forward I get the same E8000001 error message when trying to upload a new version of the app.

    I need to delete the original app off the phone and try Build & Go twice (!). Sometimes I even need to toggle the "Set Active SDK" option from Device to Simulator and back again.

    I've restored my phone since then with no luck and have no idea how to get this back to a sane state.
