Here is a step-by-step guide to install ClockworkMod Recovery on T-Mobile's Samsung Galaxy S3 [Courtesy: XDA Developers]:
How to Install ClockworkMod recovery on T-Mobile Galaxy S3
1. Download and install the latest drivers for the phone on the computer.
Download Drivers
2. Download Odin 3.04, which will be required to flash recovery.
Download Odin | Filename: Odin3-v3.04.zip
3. Extract Odin3-v3.04.zip file to the desktop on your computer.
4. Download the ClockworkMod recovery file.
Download CWM Recovery | Filename: clockworkmod.tar
5. Power off your phone and boot into download mode. This can be doneby performing a button sequence. Press and hold down the Volume Down, Home and the Power buttons simultaneously until you see a Warning message on the screen. At this point, press Volume Up button to enter download mode. A green Android logo and the Downloading progress bar will be displayed on the screen.
6. Now, launch Odin by clicking on the Odin3 v3.04.exe file which you got after extracting Odin3-v3.04.zip in step 3.
7. Then, connect the phone to your computer with an USB cable and wait until Windows finishes installing drivers. Odin will flash a message saying Added!! in the message box on the bottom left if the phone is identified successfully. If not ensure the drivers are installed correctly and also try using a different USB port - preferably a rear USB port if using a desktop computer.
8. In Odin, tap the PDA button, then choose the clockworkmod.tar file that you downloaded in step 4.
9. Do not touch any other button or make any other changes in Odin except choosing the required file as given in step 8.
10. Now, tap the START button to initiate ClockworkMod flash recovery on the phone. Once the flashing is complete, your phone should automatically reboot - and when you see the Samsung logo, you can safely disconnect the cable. Besides, you'll get a PASS confirmation message (with green background) in the left-most box at the very top of Odin. What to do if Odin gets stuck: If ODIN freezes and doesn't seem to respond, or you get a FAIL message (with red background) in ODIN, unplug the phone from the PC, close ODIN, remove battery, re-insert it, then repeat the procedure from step 6.
11. Finally, to test out ClockworkMod recovery, power off the phone. Press and hold down Volume Up, Home and then the Power button together until the screen turns on, then let them go. The phone should now boot into ClockworkMod recovery in a few seconds. Navigation through ClockworkMod recovery can be done by using the volume buttons to scroll up/down and the Home button to select an option.
Once you have successfully installed the ClockworkMod Recovery on your T-Mobile Galaxy S3 phone, you are all set to install the latest Android 4.1 Jelly Bean OS on the device.

Motorola Mobility strengthens Chicago's tech hub - Chicago Tribune
Though Chicago did not layer on financial incentives to lure the smartphone-maker from a nearby city, this appeared to be yet another example of the intraregional poaching that pits big cities against their suburban neighbors, resulting in no regional job gains.
"If you're just moving pieces on a board, it's pointless," said public policy expert Julia Sass Rubin, an associate professor at Rutgers University.
Yet this latest coup is drawing a different reaction from economists and urban strategists, who say the migration of Motorola Mobility to the central city makes sense on many levels: keeping a key tech player in the metro area; giving the company greater access to a pool of young, educated talent and a cutting-edge work environment; and putting the city a step closer to its goal of creating a tech industry cluster that could help distinguish it within the blisteringly competitive global economy.
"In a case like this, there are things that can look like a zero-sum game, but in fact, if you take a step back and look at a five- or 10-year period, this is not a choice between the city and suburbs — it is between Chicago and some other metro area," said University of Chicago economics professor Austan Goolsbee, who worked with Emanuel in President Barack Obama's White House.
Urban affairs specialist Frank Beal, executive director of Metropolis Strategies, said, "The marketplace for knowledge-based industries favors dense, urban areas — it's a global phenomenon."
Dennis Woodside, chief executive of Motorola Mobility, said a key factor in the company's decision was that its rivals are located "in places where there was a confluence of ideas and a confluence of talent, and where you're right in front of your consumer every day, so you see how people are using your devices on the train, on the subway, walking around."
Emanuel said the competition wasn't intraregional. "This is a very fluid world," he said. "People will go anywhere. This wasn't really Chicago versus Libertyville so much as it could've been Sunnyvale, Calif., where they have a big presence. Or they could've gone somewhere else. They have a big presence in the Far East."
Part of what distinguishes Motorola's move into the city is its potential to add critical mass to the city's emerging cluster of technology companies in River North.
Dan Lyne, director of technology development at World Business Chicago, the city's not-for-profit economic development agency, said the arrival of a hardware behemoth enhances the culture shift downtown.
Technology boosters point to several key ingredients for growth, including availability of venture capital investment and a robust talent pool in software and engineering. Chicago has shown promising trends in these areas, although it continues to lag coastal tech hubs such as Silicon Valley, New York and Boston.
"Everybody should take a pause, because it's hard to create clusters," Goolsbee said.
Illinois ranked eighth in high-tech employment in 2010, according to the most recent data available from TechAmerica Foundation. The state's high-tech sector employed 201,436 people and paid an average wage of $79,807. The No. 1 state in 2010 was California, with 931,000 tech industry workers and an average wage of $110,600, according to the report, which uses Bureau of Labor Statistics figures.
Illinois' ranking has stayed relatively constant in the last several years, despite a 3 percent decrease in jobs between 2009 and 2010. Tech employment has been on a downward trajectory since 2008, when employment numbered 220,064 jobs.
Still, digital startup activity appears to be nudging some of the jobs numbers upward. The sector that typically encompasses Web and mobile applications employed 61,723 people in Illinois last year, the highest figure in more than a decade, according to preliminary BLS data.
The River North neighborhood began attracting tech companies more than a decade ago because of its hip loft spaces, flexible landlords and proximity to the Central Business District, Lyne said.
Motorola Mobility will be in the same building as 1871, a center that provides flexible work and meeting space for more than 50 digital startups. Groupon Inc. has helped transform the former Montgomery Ward catalog building at 600 W. Chicago Ave. into a thriving hub for tech firms. Other companies with River North headquarters include Viewpoints, BrightTag and Trunk Club.
The potential to interact with other tech companies and organizations appealed to Motorola, Woodside said. "Absolutely, we're going to get involved in a lot of ways."
Such interaction helps employees stay in touch "with trends they better know about. ... They are less likely to go off in a bum direction," said Bill Testa, a regional economist at the Federal Reserve Bank of Chicago.
