Please Read - The Source mentioned at the footer turned out to be not real. XPeria Tipo hasn't received any Android 4.1 Jelly Bean Update. Sorry for the trouble but your Xperia Tipo and Tipo Dual are seeding the Android 4.0.4 Ice Cream Sandwich update via PC Companion tool.
A lot many devices are seen seeding Android 4.1 Jelly Bean update. Yesterday it happen to be HTC One SV, Galaxy Grand with minor update and today it turned out to be a surprise with Sony Mobiles coming to picture. Earlier today XPeria J was updated with Android 4.1 and we see Xperia Tipo also seeding with this update. Also AT&T Sony XPeria TL got this update as well with host of new features included.
Sony has delivered Android 4.1 Jelly Bean update to Xperia Tipo smartphone. Even though Xperia Tipo is an entry level smartphone available just over $200. Apparently it looks like that Sony Mobiles have setup an exclusive mindset to deliver updates to their Android phones quite often. Commenting on this update, Sony Mobiles representatives say that they have achieved expected sales about this device and it’s a big hit for them. The Android 4.1 Jelly Bean update planned about a month ago and today is the day to deliver this update.
Importantly this update will bring the Google Now integration and Project Butter as the important features added to Jelly Bean. Moreover Sony has added features like Music app, Sony live Mobile TV app bundled along with this update.
Via Sony PC Companion
Via Over the Air Update
This update is right now not available via Over the Air download. It will be available without any statement from Sony Mobiles, so keep tracing this step mentioned here. To get this update on your phone go to Settings > About Phone > Software Update > Check Now and you will be connected to Sony servers. Once you get a reply from Sony, you need to tap on Download and then Install after few seconds. Your phone would be restarted automatically once this update is installed. You can confirm the update by going through Menu > Settings > About Phone and check the Android version over there. You will see that its Android 4.1.1.
If you have this smartphone, then do let us know how do you feel once you are updated with the latest Android 4.1.1.
Tip: As the John Santosh in comments says "I got the jelly bean update for Tipo Dual via PC companion. i set my location to us but I am in India." Set your location to US and see changes.
For Your Information: I have been receiving a lot of comments on this blog post saying their phone is not seeding update or this update is not real. This update is been rolled out in experimental basis although it might be available officially in some countries.
