  • "3.5G" iPhone 4 Blazes (Where Supported)


    With little fanfare, Apple has added High-Speed Uplink Packet Access (HSUPA) support to the iPhone, and it significantly improves performance. A report in ZDNet over the weekend indicated about 60% faster downloads and a 500% in upload throughput. The results will vary depending on the support for HSPA on the local AT&T cell: in Boston, I'm getting about double the download throughput I used to get with my iPhone 3G, and somewhere between eight and ten times the upload. Zowie.

    The iPhone 4's support for HSUPA as well as High-Speed Downlink Packet Access (HSDPA, which was also supported by the iPhone 3GS) makes it Apple's first "3.5G" phone. AT&T is using HSPA as an evolutionary step towards its 4G LTE network which will begin deployment in 2011. The carrier has begun testing its advanced 3.5G network, capable of up to 7.2 Mbps downloads, in six cities - Charlotte, Chicago, Dallas, Houston, Los Angeles and Miami - with 19 more to come by sometime this year. HSUPA adds an additional transport channel called the Enhanced Dedicated Channel (E-DCH), which will allows for uploads as fast as 5.8 Mbps.

    ZDNet did their testing out in Louisville, Kentucky which - though not a major city - has a solid network: they saw downloads in the 2 to 4 Mbps range and uploads consistently around 700 Mbps. Gizmodo tested the iPhone 4 in New York, with its notoriously congested network, and still found 5 to ten times improvement in uploads.

      seems that the upload is better in the iphone4, but the most important part (download) still bout the same... I always get 2.5GB download on my 3GS

      Impressive! I wonder if some people here in San Diego are getting dropped calls every time speedtest is performed

      My best ever speeds over 3G using SpeedTest:
      Download: 385KB/s
      Upload: 40KB/s



      EDIT: And just to clarify, those are my BEST EVER speeds, typically I get ~85KB/s down and ~16KB/s up.
      You are recording your speeds in KB(kilobyte), multiply that by 8 to get kb(kilobit), which is what everyone else is using.

      I'm well-aware of the difference between kilobits and kilobytes, and I listed my speeds in kilobytes because its way more practical than kilobits. I'm also well-aware that in terms of kilobits I'm still being smoked by other people here.

      The equivalent, just because you're such a good-looking guy:
      Down: ~680 kilobits/sec
      Up: ~128 kilobits/sec

      These speeds still suck.

      if youre on the northside by the Gold Coast you will get the beta test area where you will get 7.2

      This seems like a nice upgrade. Wish there was an iPhone with a radio for tmo 3g. This is what i got when i had the HD2 .

      certain area of Detroit and Ann Arbor MI are getting those speeds. it is funny how they roll out that upgrade at the same time they change their data plans......

      I'm in Chicago (60630) and got 3220kbit/s for downloads and 607kbit/s for uploads. I wonder where exactly they're doing the testing for this.

      I'm in Charlotte and getting download spees between 3.5 and 4.5 mbps while upload speeds are around 1.5 and 2.0 mbps!!! These are super fast speeds for a 3G network. This will more than hold me over until LTE is introduced next year!

      It's sure not that speed here as AT&T needs to do some work around here. Thank GOD I have a kick butt WiFi in home. I think you can figure out what one below is home but the download like 66% of normal (22,000 kbps) LOL Daughter in Netflix. Plus a good Work WiFi as AT&T sure not pulling there weight around here. I even waited 20 minutes to see if get any better still way below advertised. Then Apple wonder why we want a better carrier that can provide what should be getting already.
