Hi there,
Thank you for this post! I'm in the UK and have just bought a French Arc S. Although it has the English language option, several icons still have the French names and I also have plenty of France-only apps installed.
Can you tell me if I can use this as the latest firmware to flash my Arc S and turn it into a generic UK model?
Thank you again 
schnide
Yes, yes you can, but why don't you install the LATEST firmware instead of this one?
