Hello. I want to upgrade my DroidX to a Sansung GS3 so that I can get 4g. I do NOT want to lose my unliminted plan. I have a buddy that has a GS 3 and he will upgrade to a Note2. How do I do this because I do not have a "chip" in my DroidX. I just activated or reset it by putting in my phone number. Can I just go to a verizon store and request a chip?
