Rooted Droid Eris on Verizon. It's pretty outdated, now but I have to wait until October before I can get a new one. Fortunately Cyanogenmod 7(2.3 based) helps keep this very slow/old processor running, stock 2.1 was miserably slow.
Sadly I don't even know what phone I'd get, the Thunderbolt is nice, but I don't like large phones and I want a phone that won't be out of date so soon.(dual core). The Incredible 2 looks good but also doesn't have a dual core processor and no 4G. Hopefully the Droid Bionic or Targa will give these things.
My wife is eligible for an upgrade(she has a dumbphone), but Verizon has no good keyboard phones right now. The Droid 2's keyboard is useless and the only other ones they have are terribly out of date.
