How to Tether the Samsung Jack on AT&T's 3G Network

 

  AT&T's 3G network requires a connection to the internet with MediaNet to enjoy 3G

Data transfer. What AT&T doesn't tell it's customers before they purchase a new 3G

phone like the Samsung Jack is that MediaNet is actually disabled by default in the

phone's 'Internet Sharing' program while tethered to a PC.

 

  This limitation prevents AT&T's 3G phones from using the faster 3G technology and only

allows connecting to the Internet through the slower GSM network while tethering.  In

speed comparison, GSM is to 3G as dial-up is to broadband.  

 

   Because the Samsung Jack is capable of blazing fast speeds with it's HSDPA 3.6

technology, by limiting the phone's connection options to the slower GSM network while

tethering is a complete waste of the phone's fantastic capabilities. However, by unlocking

the Samsung Jack's 'Internet Sharing' program the phone can then connect to MediaNet

when tethered to a PC.  This results in a noticeably faster transfer of data on AT&T's 3G

network.

 

    Here, we're going to show how to unlock the Jack's 'Internet Sharing' program to

use MediaNet and enjoy AT&T's faster 3G network while tethering.

What unlocking your 'internet sharing' program accomplishes

   In order to better understand our goal - to tether the Samsung Jack on AT&T's 3G

network - it's important to actually see the end result.  Shown below are before and after

pictures of the connection options displayed on a Samsung Jack. 

 

   The first photo shows the display screen of the Jack with a locked 'Internet Sharing'

program.  The second photo shows the benefit of unlocking this program where the

option to select MediaNet when tethering is now available.
