I'm doing something nice for my mother-in-law. She has an LG Ally that she uses to tether to her PC using PDANet. At first the Ally was fine, because all she needed was the tether. I didn't realize she'd actually learn to use the phone. Once she did, I realized how AWFUL that phone is.
In any case, a guy I work with just sold me his Droid X for $30. He went an got an iPhone, the loser (lol).
My questions for people who have done this kind of thing before:
1) Do I need to take both phones to VZW?
2) Can I just swap the SIM card out myself?
3) Any "gotchas" with doing this?
I already have possession of the Droid X, pulled the SD card and did a factory reset. The mother-in-law is visiting this weekend, so I want to make the swap as seamless / simple as possible.
Thanks in advance.
