  • iOS 4.3: Out with the Old, In with the New


    There's a number of additions in iOS 4.3 beta 1, and Mike and Wiley have covered in previous posts: improved AirPrint, support for the VeriPhone "Personal Hotspot" feature, new gestures. There are, however, also a couple of notable subtractions: support for the iPhone 3G and iPod touch 2G. Though it's not known at this time whether the ultimate release version will support the older devices, it's a sign that we're nearing end-of-life for them. At the same time, there are new device identifiers in the code, presaging next-generation iPhones and iPads.

    The iPhone 3G, released in 2008, had the same Samsung S5L8900 RISC SoC 620 MHz processor (underclocked to 412 MHz) as its predecessor, the original iPhone. And though the first-generation iPod touch shares this hardware platform (the 2G has a slightly speedier ARM11 chip), iOS 4.0 was not supported for that model, or for the original iPhone, when it was released. Though the identical iPhone 3G and iPod touch 2G were supported, iOS 4.0 ran very poorly on those devices, with improvements in iOS 4.2 marginally improving performance for some users. The fact that Apple decided to include support for newer devices and leave it out for older devices with the same hardware suggests a marketing decision rather than an engineering one. Apple didn't want to face user outrage by releasing a firmware upgrade that left out devices only two years old. As it turned out, they ended up dealing with a lawsuit about that anyway.

    There are identifiers in the new beta for iPhone4,1 and 4,2 as well as iPad2,1 iPad2,2 and iPad2,3. The original 2007 iPhone is 1,1, and the iPhone 3G is classified as 1,2, reflecting the fact that it's the same hardware platform with a slight modification (the 3G radio). The iPhone 3GS, with its improved CPU and RAM, is classified as 2,1, and the iPhone 4 is 3,1 (the Verizon iPhone is 3,2). The iPhone4,x and iPad2,x identifiers, then, suggest a significant hardware revision for the next models. Rumors have long suggested that the next generation iPhone and iPad will sport faster processors like the ARM Cortex-A9, and so the decision to cut off support for older CPUs makes sense as iOS finally moves into multicore architecture. Whether iOS 4.3 will simply not run on these devices, or merely continue to support a reduced feature set, remains to be seen.

      I understand all that but I don't agree with them not making updates for older models...people STILL use the 2 and 3G widely...we won't see them replaced for another year or so. Especially when you think about it, the iPhone. It's not an iPod where you can just dispose of it after a new one comes out.

      Fully agree.
      On 22 feb 2010, the news reported, "The price of gas has gone up 3 to 5 cents a gallon based on speculated increase in demand"

      Nobody said a word, and the price rose, and rose AGAIN shortly before Easter. This is a perfect example of corporate greed that pays out to thousands of investers. Ethical? I think not!
      Brilliant? Heck yeah
      Apple plays the same game very well, and seems to be winning. The fact is, that they make dang good hardware, pretty good software, once WE get at it, and the updates are free. If you have purchased an app, and the update of the app requires the next firmware, it is usually written somewhere in the description that it is iOS 4.0 tested. That would be your clue NOT to update. I have two ipod touch, second gen still on 3.1.3, and they do not get the 4.0 software or games. OK, so doodlejump only has four worlds instead of six. So? Still an addicting game. Pachinko works on it, and so do many other greats.
      I am satisfied.

      Bottom line, if you like apple, play the game. If not, get an Android or crackberry and beg for the latest software upgrade a month later, then go buy ANOTHER phone or pay $30.00 if the upgrade works on your phone.
