I guess this is a pretty basic question, but 1st time having to do it. I recently sent in my GS2 in for warranty work and am getting it back today. The Sprint CS Rep told me I could just re-activate it via the website when it came back in. Do I do this under the "Activate New Phone" link in my "Manage My Device" tab on the website? I was also told that there is no fee to do this, especially since this same phone was already activated on my account. Just trying to get some clarification. Thanks!
