Hello, Recently the touch screen on my Motorola Droid stopped responding. I am due for a new phone, but I may be waiting until the Razr HD(or Droid 5 if announced soon) is released within the next few months. In the mean time, I was offered to use a Droid X or Droid Bionic that a coworker is no longer using until I upgrade my phone. The Bionic has a SIM card associated with that person's information on it. If I go to the Verizon store, will they just provide me with a new SIM card to put in the phone? Will this affect anything with my contract, since I would be going to a 4G phone (Price wise or by extending the contract)? I don't want to have anything changed, since I want to use my upgrade within the next few months. I have credit remaining from the new every two program, and don't want to lose it. Thanks for your help.
