I emailed nivas post of the .jad file to myself. Clicked on the link in the email. Installed the app. It did confirm that 2.2.0 was installed and asked if I wanted to replace with 2.2.1. Once installed
Then held the left side button (the one I normally use to change profiles) spoke the word TARGET into my phone and released the button
Then a few seconds later this popped up
I am however running OS 4.2 not 4.5
