SamsungMobile.co.uk have placed a message on their Galaxy page regarding the use of unauthorised firmwares. They also state that they are working on a fix (But fail to offer any timescale)
We are aware that there is unauthorised Samsung Galaxy software currently available on the internet. This software has been produced by certain third parties to enable customers to change factory settings on the handsets. We have been made aware of instances where this software has been downloaded and has instead resulted in permanent damage to handsets. Downloading unauthorised software may also result in invalidation of your warranty.
At the moment there is no "official home update solution" available for the Samsung Galaxy handset. However we are currently working towards a solution which will be made available on this site. Neither ourselves, nor the operators can be held responsible if you choose to download unauthorised software from a third party. This software may also not be virus free. We therefore ask you to exercise appropriate caution.

Thank you
