Their new phones might come with 2.2 Froyo, or with 2.3 Gingerbread...but I'm thinking...2.2 Froyo...then the manufacturer pushed the updated software to the phones when they feel like it.
I looked online at Verizon...looking at all sorts of android phones available...and I didn't see one phone with the 2.3 Gingerbread pre-installed. I didn't look at ALL the phones...but just the ones I had interest in.
It's worth your daughter and her SO knowing about the issues that can arise when one OS is layed on top of a pre-existing one.
It's supposed to be a software UPDATE. It didn't say it was a totally new thing. I wish I had never been duped into downloading and installing it.
It's crossed my mind...maybe it's a plot to ruin older android models so that you'll upgrade to the latest piece of candy. The old Conspiracy Theory!
