For those using the 10C/10M mods with no issues... the 10R mod should continue to work the same.
For those unable to get around the "Account Upgrade Required" message.. try harder.
For those having issues with data working after changing to ipv4... not sure what to tell you. It may be a local/regional thing where they are disabling ipv4.. or it could be something else.. who knows. It works just fine for me.. and tons of people use this daily with no issues at all. Perhaps try making an entirely new APN with only the ipv4 stuff?
