Just received this from Orange.
"Hello,
We just wanted to let you know that Microsoft has launched a new operating system called Windows Vista. If you’re not planning on using Windows Vista, please don’t worry, your broadband service won’t be affected.
If however you are planning on buying a new PC, or upgrading your existing one to Windows Vista, we need to make you aware that it may have an impact on your Orange broadband service, as your USB modem might not work.
Don’t worry, we’re working towards fully supporting Windows Vista and in the meantime, we can still help you get connected. Just visit our online help section
www.orange.co.uk/vista for all the information you’ll need.
Sorry for any inconvenience this might cause.
Thanks
Customer Support"
