You'll need to edit this file: C:\Program Files\Common Files\Research In Motion\Shared\Loader Files\8830-v4.2.2.66_P3.0.0.45 (or your version)\BlackBerry.alx Then all you do is open BB Desktop Manager and run apps loader. Your os should show "update" proceed and all should be good!!
BTW, I have the Verizon 8830 and here is a clip of want my alx reads after editing, note where I edited "105" as the vendor Id as I have the Verizon version. Hence if you have AT&T is would be "102" - Sprint "104" ....so on. Good luck all, If anone needs any help send me your text and I will edit it for you.
