For someone currently happily using a dumbphone, who recently had an embarrassing experience that could have been prevented if I had a GPS and is now considering drinking the kool-aid, what can you tell me about the standard disclaimers? I know that rooting the phone means you lose your warranty, but what I'm not sure of is a) how easy is it to restore the original ROM so that VZW can't tell the difference, b) how much value a warranty has anyway. When my last cell phone broke Verizon didn't offer to fix it, I had to get a new phone using an upgrade.
