Remove your battery to see your model #.

Interesting. I don't completely know what to make of this but it looks like there are two revisions for the AT&T unit. They were both certifying software at the same time though? The last model posted I assume has been halted and replaced by the top one.

.384 seems to be the latest stable version so I hope it leaks soon.

What does all of this mean? How can I check which version mine is?

If T-Mobile USA is testing .384, and we know that someone on this forum has had UMA on their 9900 with T-Mobile USA, does this mean that .384 may be the build we need to be leaked in order to add UMA?

*UMA = UMA or GAN-lite in my post
