Hello acappetta! The operating system on the LG Revolution should still be Froyo, as that device has not received updates to the next operating system release (Gingergbread). What you should check is the Baseband Version. That will let you know if your device is up to date. Go to Settings> About phone> Baseband version. The most recent version is VS910ZV9. If you do not see that, please allow 2 weeks for the latest update to roll to the phone. Thanks!

It is funny, LG official support website for lg-VS910-revolution offere that upgrade tools for LG revolution.
But it is "not a supported device"....
A good reason to leave LG away...
I went into a verizon store this afternoon to see if they could do anything regarding having the update file on their servers. They could not, so I hopped on ebay and forked over the 200 dollars for a brand new droid bionic. never owning LG phones again.
