All AT&T SIM Cards Work Now

[bconnor]

Does a Cingular Sim work? I ask this because before the firmware update to include sudo-GPS my iphone 2G was not required to be unlocked with that sim. Just jailborken/hactivated was needed for a working 2G iphone.

i don't know, all i have is my old at&t sim card. you can try it; it's not difficult at all to downgrade back to 1.1.4. just make sure you know the difference between DFU and recovery modes, so you don't freak out about messing up your phone.

Wow, I must be really confused. I thought the whole point was that you could take a pay as you go sim or an old att sim and put it into a 3g iphone? It's almost 100% not going to work if i upgrade to 2.0 on my 2g iphone because I can't hactivate/jailbrake/unlock without pwnage 2.0. I will just have an activate screen in itunes.

Unless I'm reading this whole thread wrong?

Well with my 1st gen iphione i got my SIM from AT&T and activated it over the phone then i put it in my unlocked 1.1.4 phone in order to use Swirly MMS.

The other day i updated to 2.0 and it worked fine with my SIM card as soon as i connected it to iTunes. I was surprised that it worked that way and figured that 2.0 had the feature. My SIM was NEVER activated with iTunes nor was it the SIM that i received with my iPhone.

Just came back from the AT&T store and talked to one of there consultants... it is confirmed that you can change the "phone/device" from your at&t account to the 1st gen iphone and downgrade your data/text plan back to the $40 one. the reason the sales consultant said it was higher was to level the playing field with the blackberry and other PDA devices that pay a cheaper data plan. He also explained that they get a commission on the 3G data plan and that's why there pushing it. Like i said on the last page when you sign up for the 700MIN Family talk which is the minimum you can simply log into your AT&T account and change it to the cheaper 550MIN Family plan with no repercussions. He also confirmed that any "NEW" AT&T SIM card will work in the 3G phones.

I think kline1 is the one who needs to do the reading...

So I can go to my ATT account online and change my phone to just Iphone from my current 3g and then sign up for a $20 data plan. No ETF that has to be wrong.

alrite soo...

i have this unlimited min plan from att for 49.99 for yrs... and i DO NOT WANT TO LOOSE it......and i have a cingular 3g sim card from b4 when att took over.... ne ways any one confirm that if that simcard will work with the 3g iphone??? or the only new att cards work??

[eclipseballer08]

I also have an old unlimited AT&T plan for really cheap and I just want to make sure there is no way AT&T would find out that i have the iPhone (otherwise they will cancel the plan.) so just to make sure before I upgrade to 2.0, is there any way that AT&T will know by doing this that I am using an iphone (instead of the old piece of crap LG they think I am using it with?)

Yeah, your phone will send it's IMEI(International Mobile Electronic Device Identification) number the AT&T's system and they'll know you have an iPhone.

But under the unlock/jailbreak method, did it do that then too?

[sagacious1]

I tried switching my sim cards--both active AT&T numbers--after upgrading to 2.0. What I got was the activation screen indicating that I must reconnect to iTunes. I didn't pursue that because I feared I would lose sync data. Is that true, or will it just sync all previous songs, vids, etc. under the new number??

My 3G is on order--I tried the switch with a 2G iPhone upgraded to 2.0

[babybia175]

Ok so I'm still a bit confused. I own a 2gen iphone with 1.1.4 unlocked and jailbroken, but I still use at&t. So from what I just read I can update to 2.0 without locking my phone or have to register it?

does anyone know if this can be done? i'm curious, i've got a 1st gen iphone at 1.1.4 unlocked/jailbroken, but it's ATT. those apps sitting in itunes are killing me so i was wondering if anyone knows whether or not this is true...

[kdeshana]

I want to buy a new iphone for my husband but at&t wont let me get a contract bcuz of my credit score...I wanted to use a go phone sim card but they said I can't. Anybody know what I can do? Please help...he really wants an iphone

Hi folks, we've updated the original article with new details, you can read it at the link below:

Yup this post is all true! I bought an iPhone 3G thats already activated from craigslist and I popped in my gophone sim card, restored the iphone (yup restored!) , and it activated!!! now i can use my iPhone 3G with a $20 unlimited data!!!

Any current At&T customer can buy an already-activated iPhone from ebay, craigslist, or from your friend and just put in your own at&t sim card and your good to go!!!! the iPhone isnt locked to a specific sim anymore, its just locked to at&t which is whats normal for carrier subsidized phones!!!
