help, at&t contract on 3gs

[amitash]

hey, i want to go and upgrade to an iphone 3gs, i went to at&t and they told me they would witht he 2 year contract...the problem is that, i want to keep switching between the iphone and an old cellphone that i have, now the guy at at&t told me that they wouldnt give me a sim card with the iphone! they said they will activate it wirelessly or some crap like that without a sim...my questions are:

1.will they really not give a sim card?
2.if they do give me a sim, can i put it in an other phone and still avail the connection to make calls, text etc? i need to keep switching between phones, so will the sim work on another phone? i will pay the contract and everything


All at&t iphone users please help

I swap my sim card all the time. I have my iPhone during the day and when i am out at night or Hiking in the woods, I switch to an old Nokia. I would rather lose an old phone then my iPhone.

PS. buy from Apple store, they are so much more professional then an ATT store. I went to ATT once and all they did was try to lie, cheat and steal.

The iPhone will come with a SIM, but they may remove it and put your old one in it if it's a 3G SIM. If they don't put your old one in it, the new one (that comes with the iPhone) will activate through iTunes and the old one will deactivate. All GSM (AT&T and T-Mobile are GSM carriers) phones need SIM cards. You can swap it between phones as you like. You eject the SIM tray with the included SIM ejector tool, but a paper clip works just fine if you don't have one.
