I have the AT&amp;T Samsung Android Mobile with 2.3.5 OS and it's model no is SGH-I897. Now I want to upgrade my mobile os to lates 4.1 or 4.2, So can any body help me how to do that. Thanks in Advance.
Android 4.1 (Jelly Bean) was announced at Google I|O 2012 on June 27, 2012.  (You can review  at the official Android Developer's site.)  Of course, not all devices will get this update right away and others won't get it at all. Each manufacturer and carrier often choose to add their custom modifications which tend to delay the official release.  When will each device get Android 4.1, either officially or unofficially, if ever?  See also:
How to call child component controller function/helper from Parent Component Controller I have searched in %appdata%, pulling up the list of files there, but there is no file labelled .minecraft. Searching %appdata%\.minecraft returns "no results found".   I also opened Minecraft to click on the resources button and could not locate that either. Can you get to blocked-in areas? Can the Force be used to fly? In The Empire Strikes Back Yoda uses the Force to lift Luke's X-Wing out of the water and put it on land.  In Attack of the Clones and in many instances in the second series of The Clone Wars, Anakin (and others) use the Force to jump higher than they could otherwise, or to jump from very high locations, but I don't think I've ever seen the Force used for outright self-levitation.  But if Yoda could lift the X-Wing, shouldn't a strong Jedi be able to lift himself and, essentially, fly with the help of the Force? Time Dilation inside a hollow shell Assuming I have a hollow shell with total mass $M$ and radius $r$. On the surface, the gravitational time dilation would be  $$\tau=t \cdot \sqrt{1-\frac{v_{esc}^2}{c^2}}$$  where  $$v_{esc} = \sqrt{\frac{2 \cdot G \cdot M}{r}}$$  but inside the shell there would be no gravitational field (Newton's shell theorem and Birkhoff's theorem).  But still, the escape velocity required to escape to infinity would be the same as on the surface, since inside the shell you could move without any accelerating or decelerating forces acting on you until you reach the surface, from where you would get pulled backwards.  So is the time dilation inside the hollow shell relative to a field free observer at infinity    zero (I assume it's not) or  the same as on the surface (my best guess), or something completely different?   I found some not really duplicate but related threads on the interior of black holes which did not really focus on the math, but I am more behind the calculations in terms of $M$ and $r$. What are the use cases of SO_REUSEADDR? I have used SO_REUSEADDR to have my server which got terminated to restart with out complaining that the socket is already is in use. I was wondering if there are other uses of SO_REUSEADDR? Have anyone used the socket option for other than the said purpose? Why don't we feel the subtle speed change of Earth's elliptical orbit? Earth's orbit is a slight ellipse, so to conserve momentum its speed increases when it is closest to the Sun. If the speed changes there is an acceleration. If there is an acceleration there is a force. Even if the change is small and gradual, wouldn't we experience a force because the Earth is so massive? Can I secretly kill every guard in a town? Is it possible to kill all of the guards in a town?  Ideally, I'd like to do this secretly so the entire town doesn't see my deeds and put a bounty on my head.  Edit: I was questing in Markarth and was told by a guard to back off and stop being nosy. I didn't and when I went to the Shrine of Talos I was set upon by a bunch of guards.  Now I have a huge bounty and I had to sneak/kill my way out of the city.  Every time I killed a group of guards the bounty was reduced by $1000, but I still have a $30,000 bounty.  I haven't even been through 1/3 of the city yet and know there has to be a lot of quests, so what do I do?  The only solution seems to kill every single guard (and inhabitant). How are questions in the 'hot' tab on a site selected? I know questions on the "hot" tab of a site homepage are based on some sort of views/velocity criteria, but does anyone know the actual algorithm used?  Background: I was considering a feature-request about the "hot" tab, but I don't have enough information to speak about it intelligently. I have read that a holomorphic function in an open disc has a primitive in that disc. Does this mean that for any holomorphic function $f$ in any open set $U,$ that $f$ has a primitive? I say this because I can take a large enough open disc to cover the open set $U$ and find its primitive there. Is this a correct way of thinking? Sauron knew that the One Ring could be destroyed only in Mount Doom, where it was forged. From Sauron's perspective, no one would think about destroying the One Ring. But if someone did, then Mount Doom would be the only place to do so.  Why did he keep Mount Doom active? Wasn't the risk too high? How do I find this conditional expectation? When searching for "Skype" I always see these 2 entries.  There is this duplicate blank Skype icon. Both of them seem to run Skype in the same way.    But I've checked both /usr/share/applications, and ~/.local/share/applications, and can't find the extra icon so I can delete it.    Also as described , sometimes similar ghost icons are present even after removing associated applications. ASP.NET Stress Testing Is there a way to test an application where you simulate a hundred different clients connecting to a IIS server and asking the same data? At the customer where our project is running they have 400 computers and they often do stress tests with all computers. I on the other hand have only got my laptop... (and a development server).  (In my case the data is asked through a WebORB Gateway). Can you please guide me best way to retrieve all active picklist values of all recordtypes of object.

Improved Help Center - site-specific pages and site-specific edits to all pages Right now, moderators can edit some pages in a site's Help Center. For example, the entire /help/on-topic page can be edited. However, the /help/dont-ask page can't be edited at all.  I'd like to see two changes to the Help Center:   All pages should be editable by site moderators. Some pages do apply to all sites, such as the /help/dont-ask page I mentioned above. However, it may be useful to edit in some site-specific guidance. The entire page doesn't need to be editable in order to ensure that key commonalities across the network remain in place on all sites. This uneditable content should be at the top of the page and moderators should be able to add site-specific content to the bottom. Moderators should be able to add new pages. Instead of maintaining meta tag [faq], FAQs can be added right into the Help Center from Meta. The Help Center serves as a single point of reference for the community rules, norms, and policies. Meta questions can be used to discuss updates to pages. This avoids issues such as question and answer ownership and the ability to accept/change accepted answers as users come and go from a site. An active site will always have diamond moderators to perform the edits to the Help Center.   Note that site-specific pages do already exist. , which no other sites have. This is something relevant to Stack Overflow (and perhaps a few other sites). It would be nice to allow sites that have this policy to link to their own Help Center for it and to edit the page to provide additional examples that may be relevant to their user base.
