The iPhone 4S officially went on sale in the US yesterday, and unsurprisingly, it has provided record-setting sales for at least two of the three major U.S carriers that offer the device.

AT&T on Friday confirmed to BGR in an email that it has activated a record number of iPhones and is on track to double its previous record of activations in a single day.

Sprint, which didn’t start carrying the iPhone until this month, reported its best ever day of sales in retail, web, and telesales for a device family in Sprint history, thanks to the launch of the new iPhone 4S and iPhone 4…

Sprint Product Chief, Fared Adib:

“Sprint today reported its best ever day of sales in retail, web and telesales for a device family in Sprint history with the launch of iPhone 4S and iPhone 4. We reached this milestone at approximately noon CT/1pm ET. The response to this device by current and new customers has surpassed our expectations and validates our customers’ desire for a truly unlimited data pricing plan.”

Sprint is the only U.S. iPhone carrier that currently offers an unlimited data plan to its customers.

These numbers probably explain the activation issues new iPhone owners were facing yesterday.

    I need help. I just upgraded my iphone 4 to ios5 with a baseband preserved to 4.10.01, but I’m stuck in the activation screen. My phone is locked to ATT and I’m sure of it, but now I even can’t activate it with my friend’s ATT sim card, it still says that the sim is not compatible. I wonder if the phone requires the orginal sim card or can be activated by any ATT sim card like many said? If so, what happens to my phone? I had my original ATT sim but I’m sure I can’t find it anymore. Please help me.

    • I think u need I iPhone sim card

    • Cody

      That’s weird nothing’s wrong with me here

      • kyle

        did u activate your phone with ur original sim or other sim?

    • Siri

      I’m in the exact same position as you. (modle, baseband, firmware)

  • Cody

    Or maybe you could go to the at&t customer care and ask for a new sim

    • kyle

      but i’m not an att customer, i’m using other carrier, i used gevey for the unlock and i just wanna activate the iOS to continue with the unlock

      • Keith

        Take it to apple

  • where is the numbers??!!? i wanna know how much iPhones!!

    well i guess apple is maybe holding off so they can tell it officially.

  • Steel

    Wish I could get my money back from AT&T, nothing special about the new vs the 4, (buyers remorse)

    • J-

      Trolling huh. Of course you can get your money back. I believe you gave 14 days under AT&T.

  • Tommy

    Why would you preserve ya baseband if you aint usig it unlocked unless you wanna custom firmware but only time inuse a custom is to make more space and give it more memory

    • kyle

      i preserve my bb because i wanna keep using gevey, which supports only my old bb.
