Will my cingular sim card work with a new att cell phone?

I currently have a plan that I got about 3 to 4 years ago when it was cingular, so I have a sim card that says its a 64k smartchip. But I am wondering if I were to but a new att phone today would it work with the sim card that I have?

1. yea i am pretty sure it still works
2. It most likely will unless the new phone is locked to ATT use only and doesn't recognize the older Cingular sIm. Because they merged it can probably be used in the newer phone. Cell phone carriers that sell phones requiring sims usually lock their phones so they can only use their own company's sims. If you have been with a carrier for a while they will usually provide you with the code to unlock the new phone if it is required.
3. It would work depending on if you have data feature's in your plan such as MEdia net or IM the would have to send you data encoding for your sim card from thier network so your new phone can be fully accessible with the feature(s), also you can get a unlcocked phone with out all the trouble, but if you want basic calls and text then it should work just fine.
4. Most likely it will. The best place I have found to buy a phone without a contract is: http://www.myphonedied.com
