Number change for France Telecom's English language helpline
The number is 09 69 36 39 00, although the call is no longer free and is charged at a so-called 'standard rate' which I've tried to source but drawn a blank.
The France Telecom Contact Us page provides details of the number you can call in France, as well as how to call if you are outside the country, +33 (0)9 69 36 39 00.
France Telecom has also swapped the options around, so the first one is for technical questions about your telephone and internet access, whilst the second is for account queries and setting up a line.
France Telecom's English-language helpline is open Monday to Friday, between 9am and 5pm.
Update (26/11/09): Thanks to Geoff in the comments another telephone number is available enabling you to contact the English language service from France Telecom for free - 01.55.78.60.56
