I just found the following directions online from ehow, but it raised another question (see point 4)
Since Verizon doesn't use a SIM card, would it be correct to say if I did a factory reset, deleted all contacts, messages, photos, etc the phone would be good to go to be sold?
How would the new owner set up service if Verizon didn't use a SIM, and they were locked into using Verizon? I'm a dumb bunny when it comes to that sort of thing, but I'd like to know.
BTW, I've looked at what the phone is selling for on ebay, and I figure if someone is willing to buy it, it's their issue if they feel they want another phone in 6 months.
Ensure that the phone is in working order with no missing pieces before you offer it for sale. Be honest when you sell used cell phones, as with anything else.
Delete all contacts, photos, and other personal information from your phone and/or save it all to the phones SIM card, if it has one, or back up any data to a PC or other source that you want to keep or transfer to a new phone.
Look in your instruction manual or online to find out how to do a factory reset on your phone; this ensures you didn't leave any private information on the phone and gives the new user the ability to set it up from factory defaults just like you did.
Remove your memory card or SIM card if applicable to your cell phone model. AT&T and T-Mobile use SIM cards, whereas Verizon does not.
Keep your SIM card; the phone's buyer must use his old SIM card or get a new one from a dealer. The SIM cards always stay with the original owner for cell number, privacy and billing purposes.
