I bought a vibrant from a friend that needed money. I have had much fun figureing out how to unlock it but found a easy way and thats done. Now I see my current carrier (boost) runs on i-den and the galaxy is gsm? and it wont work with boost. question 1- am i correct there is no way possiable for this phone to run on boost? question 2- If so what networks can it run on that are similiar to boost? (I enjoy no contracts,unlimited everything and its kinda cheep ) Thank you! also..I just updated the firmware and after I did, I know have a signal its seems (the lil bars that light up for signal strength are jumpin around) it also says im regestered when i hit the auto select preferred network with boost sim card in..but dialer says not regestered to a network?
