Hello all,

I'm activating my Bold 9900 tonight and before I do should I dump the 7.0.0.57 that's on there and upgrade it to the most react OS or is there a particular one I should go with?

Thank you for all your help in advance

I've found 7.1.0.580 to be the best for battery life. Good luck!

I am also using .580 but you might want to try others later. Just choose one and run it for a while to see how it treats you.
You can always upgrade later.

The OP has a 9900 and .580 isn't available for that.

The BL .714 hybrid wins the prize in my book.

What's the difference between the hybrid .714 and the leaked .714?

Faster, smoother, quicker browser, better battery life.

7.1.0.714 works fine for me.

What legaleagle says. And add in functionality for ATT. Most other OS have a mic issue on ATT.

There is a Special Edition BL Hybrid for AT&T users using .694 OS as base to avoid the Mic issues.

The normal BL series, latest version RC7B1, will work best on base OS .714 or .658.
