Motorola V620

First of all I love this phone. It's perfect in almost every way. But there are a few things I'm having trouble with. The roam indictator is on. I went to Cingular and the guy said not to worry about it but I still want to turn it off. Another thing is that the language settings are set for the UK. I know this is a European phone but I don't like how everything is spelled differently(personalise, centre, etc.) And finally I can't get MMS to work right. I get the messages but it's just the heading with a weird symbol. I tried all the settings from a previous post but it doesn't seem to be working. Thanks in advance to anyone that helps. BTW I have Cingular.
