First, I read the article and comments here: http://samsungvibranthacks.com/samsung-vibrant-hacks/how-to-usb-tether-your-samsung-vibrant/
I tried following directions, but tethering only works on the older version of the kies software; see below:
I am having the EXACT SAME PROBLEM as many users. I'm trying to tether my laptop to my Samsung Vibrant using Samsung Kies version Kies_1.5.3.10093_82 and Android version 2.1 update-1: I'm beginning to believe that T-mobile doesn't want us to use our phones to connect to the internet... They'd rather sell us a T-mobile Broadband card.
T-mobile, I paid top dollar for this phone, I expect it to be fully functional!!!
Guess What: I just installed an older version of Samsung Kies; version: Kies_1.5.1.10071_32 and My phone hooked right up (after I applied the connection properties etc.) Looks like that version can be downloaded from this site:http://www.4shared.com/file/cSreYUQN/Kies_15110071_32.html (I do not guarantee this download. Download at your own risk. I did not download the version from this source, just did a google search to find it.)
