Currently have the OG DROID and looking to upgrade to a new phone. Any suggestions on which one to get?
It would probably be beneficial if you said what was important in a smartphone to you. Both are excellent phones, but they suit different needs. There are also hundreds (literally) of threads discussing this exact topic.
Nexus or Razr?
Just a couple I came across from google. I'd start there if I were you and if you have additional questions, you can always come back to this thread.
Don't be scared, adb is your friend.
