    From what I remember the 4S and 4 do not have the same speed. The 4 tops out at 7mb I believe and the 4S at either 14 or 21. Can't remember off the top of my head which one it is. But the 4S is faster.

    Yup, just checked. The iPhone 4 has 7.2mb HSDPA. The 4S has 14.4mb HSDPA.

    I believe thats for 3G/4G speeds only
    AT&T delivers at a max of like 14mbps over 4G while everyone else can only do 7mbps right now

    on wifi I just got a return of 38mbps download and 7mbps upload on an iphone4S

    My Internet actual speed is 50mbps down and about 5mbps up

    Thus technically the phone can go faster but the drawback is your provider
    When I had an iPhone 4 I did the same test hitting about 20mbps download and 5mbps upload

    Yes. AT&T only.

    That is incorrect. AT&T can deliver 7.2Mb/s on 3G. HSPA+ is 4G and yields 14.2Mb/s.

    I get this on my 4S. Have actually topped out at 10mb before. My iPhone 4 would always be in the 5-6mb range on the same network.

    7.2 Mbps on EV-DO Rev. A?! Lol in what world?

    Likewise, the iPhone 4S is a 14.4 Mbps HSDPA device, not HSPA+.

    Some fact checking is in order.

    That is incorrect. AT&T can deliver 7.2Mb/s on 3G. HSPA+ is 4G and yields 14.2Mb/s.
    14.4 Mbps HSDPA is still considered 3G as it is no where near the theoretical maximum speeds of HSPA+, LTE, and/or WiMAX.

    And no, not AT&T only. Well maybe the software update. However, all iPhone 4Ss are capable of 14.4 Mbps (or Mb/s) over HSDPA.

    AT&T can deliver a theoretical maximum of 21 Mbps HSPA+ on their network (where they've deployed it). There's no magic switch to toggle between HSPA+ and HSPA. The only thing that would limit connectivity to HSPA+ is the device. An iPhone 4S connected to a 42 Mbps HSPA+ network is still an HSDPA device. Yes, it will be closer to reaching its theoretical maximum, but it does not automagically make it a 4G device. There is no [efficient] way to determine if a device is connected to an HSPA+ cell or an HSPA (D and U) cell. So AT&T and Apple opted to slap a "4G" icon on the 4S once it's connected to 3G (HSPA). I do wonder if the "3G" icon would show up if the phone connected to a W-CDMA-only cell though.

    Shame on Apple and AT&T.

    And you have a real network similar to T-Mobile USA. Oh AT&T...

    Actually, this is not true. An iPhone 4s on AT&Ts' network will always have the "4G" indicator even if your iPhone is connected using a "3G" protocol! The ONLY thing that the "4G" indicator means is that you are NOT on the EDGE network.
