We are also getting reports that O2 users in the UK are finally getting the update to 1.29.401.7, which is good news, as a late update is better than no update.
To check and see if this OTA update is available for you, just go to Settings > About phone > Software updates. As always, if you are rooted, you should proceed with caution as you could lose root abilities. For all others, enjoy the update, and let us know if you notice anything else that’s updated.
