I have an unrooted stock droid. I upgraded to 2.2 yesterday with one of the many how to guides from people who are not willing to wait for Verizon to push it thru. I installed it and it works fine, the only issue is my charging port has been acting up and finally completely died and I want to take back to Verizon for a swap. I am afraid they will not give me another phone if I have the update already on my phone, even though I am not rooted. Can someone please help me on how to go in reverse if even possible. Thank you.
