If you have an HTC Sensation on O2 in the UK, you've likely been wondering what the heck has been taking them so long to push out the Android 2.3.4 update. Truth is, we don't know. But, they've finally managed to get it together and make it available for download.
Customers of O2 started reporting the update being available as of early this morning and now it seems a full roll out is happening. Go ahead and check for system updates, you'll be pleasantly surprised to find it there waiting for you.
