A:AnswerI had mine shipped. It's from Best Buy so if they have it in store you can choose to pick it up. Otherwise you will need to have it shipped. I will be taking it to my carrier to buy a simcard and activate it.
A:AnswerYes, you can use any carrier as long as they use the specific "frequency" or "type" as the phone. There are two types and you need to make sure that the carrier supports that type on your phone or you can not use it. There is the one for ATT & Verizon (GSM or something like that) and a different one for Sprint. Do some research before you purchase any phone. Also, the "warranty" is not through Apple so you will have to send it in for any issues or return it to the store (and there are no on site replacement).
A:AnswerThis phone came with a charger; no ear buds. You will need to purchase your sims card to use the phone. I can't tell you shipping costs but you can go online and get an estimate. The warranty is through a 3rd party carrier, not Apple. I received a phone that didn't have a "closed case" and would not hold a charge. Apple will not repair it under the warranty and you will need to send it into the 3rd party if you have an issue.
A:AnswerYes if you use the correct version. There are two. Check to see which one your carrier uses and purchase the correct one. Verizon and ATT use the GSM version and Sprint a different one. You will need to determine which phone to buy based on that.
