If you are one of those people who needs to have their upgrade now and don’t want wait for Samsung to release it for your country or your country is not listed, you can change your current WM5 firmware to generic, then to a country that is listed on the WM6 upgrade pages (http://www.samsungmobile.com/promotion/i600/index.jsp)

The details are listed
here.

The process in short is:

1. Download and install no brand firmware from http://wiki.modaco.com/index.php/Samsung_i600#Latest_Official_ROM_Downloads (first you will need Active Sync 4.5 and modem drivers from the file installed, then run upgrade)

2. Switch phone to Netherlands

– type on phone *#1546792*# (or run hidden program in WindowsAdminSettings.exe) to get to admin settings menu
– chose option "Preconfiguration"
– type password: *#81230*#

– select operator: Vodafone

3. Download and install WM6 upgrade. (see http://www.sems.org/entry.asp?ENTRY_ID=254 for download
