Microsoft revealed on Wednesday that it is now delivering the Windows Phone 7.5 update to Samsung Omnia 7 devices on the SFR network.

SFR users in France will start to see the Windows Phone 7.5 “Mango” update show up on their devices from Wednesday. Microsoft is still delivering the Windows Phone 7.5 update to 50% of Windows Phone users. Microsoft’s Eric Hautala, in charge of Windows Phone update deliveries, had no further information to share on additional devices for Mango. “Your global adoption, use, and feedback is helping us make delivery decisions,” said Hautala in a blog post on Wednesday.

Spanish operator Telefonica is still testing its Mango update for devices. “I’ve seen some questions here and on Facebook about phones still listed as testing on Where’s My Phone Update?” said Hautala. “ If you own one, I want to reassure you that we’re working closely with carriers to complete testing and are making good progress.” Microsoft will add more phones to the Windows Phone 7.5 update pool in the coming weeks. AT&T customers with the Samsung Focus v. 1.4 and Dell Venue Pro are still waiting for the carrier to complete testing.
