Wife's iPhone 4 sim card put into daughter's iPhone 4s?

It can. You are just required to sign a new 2 year contract on the line that has the available upgrade. What you do with the phone after that is your business.

 

Yes. Just swap the sim cards. I used my brothers upgrade to get my 4s. And he will use mine when it's available in march.

 

no it doesn't matter

 

I've done this multiple times on Verizon and AT&T.

For example, I was eligible for an upgrade, but my phone was fine. My daughter had just lost her phone off the top of a roller coaster (long story). We used my upgrade to get a new phone for my daughter. The customer service rep sold me the new phone and then even helped us switch the numbers back (on Verizon at the time) so I had my number on my old phone and my daughter had the new phone with her number. The downside is that I was stuck with a two-year-old phone and a new two-year contract.

I have done something similar using AT&T sim cards years ago.

 

Ok don't believe me then. I'm not sure why its so unbelievable?

 

AT&T even tells you how to do it on their website.

 

Then don't believe it. People gave you the answer and you won't believe. Just call your carrier and ask them if you don't believe us!

 

Interesting....care to go into that a little more?

 

OP probably got into a huge fight with his wife about this, trying to act all smart and **** and now he has to break them the truth that he, in fact, was the one that was wrong.

that's why he needed to post a few times for reassurance.

 

Your wife is right it can be done

 

My wife used my upgrade to get the 4s. No big deal, except that now I'm not eligible for an upgrade until 2013.

 

used wifes upgrade to get my 4s. Saved my upgrade for the next iteration of the iPhone. BOO YA!

 

I have two extra lines (fathers and aunts) that have upgrades in September and October which I'm hoping is the time frame for the next iPhone. they both have new flip phones which suit their needs just fine.

 

Unlocking allows a phone to be used on a GSM network that the phone was not carrier-locked to.

OT:This is not 9gag/4chan, so these memes here are very out of place.
