I got a T-mobile Vibrant a few months ago. That is Samsung's Galaxy S smartphone. I can tell you that I did not stay with the stock ROM for long. At first I had no way to access the phone through a computer as I hadn't received the USB cable connection. As soon as I bought a new one, I was on the hunt for the right ROM. At first I updated to Samsung's other official ROM, which was the new FROYO 2.2. The phone had come with Android OS 2.1. Not being satisfied, and looking for as much awesome as possible, I went over to xda-developers.com They have a section specifically for the Samsung Vibrant, here. Over in the Android Development section you will find ROMS, Kernels etc for your perusal. Below is a recall of the ROMS I tested. I will cover how to install each in a future post.
First:
Bionix 1.3.1 found here
I originally found this ROM through XDA but it is easier to find on the ROMS official site. It was a decent experience, and I thought it would be the best ROM I could try, especially after my attempt at using the next ROM in this list. A review of the ROM is provided below along with pics and some features.
