The right iphone sim card?


I have a 1st-Gen-4GB-Iphone which loses service frequently (cant make or receive calls). At&t and Apple both think its a damaged sim card so they switched it out for me. But now I notice they gave me a 3g sim card and my phone still doesnt work? Do I entail a 2g sim card or does it not matter? Thanks

Best Answer:
They know best which sim card you need. Either the phone is defective or your service is. You could be in a fringe nouns also. Go to the ATT store, the Apple store and do not give up. One of the will find the problem and fix it.



3G Iphone cross-question...?
been with sprint for a while but planning to leave inside the next few weeks, i was reading about the Iphone voice I get a 3G Iphone with a 2 yr contract with ATT. Whats the difference between unlock and jailbreak? and if I do that will it effect my contract end in I am the type that like to get free movies, games, ect..., will I get caught doing that beneath contract?or will I need to jail break or unlock if I am under contract? what are the best free websites or softwares for doing that? | Unlock resources you can use your iphone in any GSM around the world. Jailbreak but not unlock is you can istall more apps for free that is not available on itunes apps store/apps store on iphone and still locked for AT&T (means you cannot use the iphone with tmobile or any gsm provider but AT&T)When you unlock your iphone it is also jailbroken.. you cannot of late unlock the iphone if it is not jailbroken.The good of jailbroken and unlock - you can swap sim cards anytime and more free applications for you.The bad is you voided your warranty on apple. But you can always re-jailbreak it and put it put money on to factory settings so you can return it.Start with http://www.iclarified.com/entries/index.php?caid=2&scid=11&seid=1 | I'm not sure about the unlocking, but I recently switched to At&t from Sprint myself, and I can't convey you how much better it is, better reception, better customer service, better cell phones, the list is just neverending, I would recommend the switch to anyone.. Hope this helps. :-)
