i didn't think it would, i just wasn't sure so i figure i ask, cuz i've been reading and it seems like a lot of people have been having problems with beta firmware so i didn't know if it was worth installing it or not.
There are some issues, but there is no difference (from what I can tell) between b3 in Canada on Rogers, and b3 on AT&T in the US. I use b3 daily, and it works for what I need.
