The iPhone 3GS supports 7.2Mbps connectivity; however, these kind of speeds won't be obtained if you are trying to upload, according to a MacWorld report.

Macworld reader Nick Dunklee points out that a teardown at RapidRepair of an iPhone 3GS shows that it has a UMTS/HSDPA chip. UMTS is the earliest 3G standard deployed on GSM networks, and it tops out at 384 Kbps. It’s easy to test, if you have an iPhone 3GS. Go to any speed tester, like Testmyiphone when you’re outdoors with a good signal. Downstream, you might hit well over 1 Mbps; upstream, under 384 Kbps.

Unfortunately this seriously limits the upload speed of your iPhone. Those who upload photos and video regularly will not be able to take advantage of the higher speed network.

Its likely that Apple will introduce this in a future model of the iPhone as a 'New Feature'.

HSDPA is High Speed DOWNLINK Packet Access which gives you higher DOWNLOAD speeds while sending data tops at UMTS PS speeds - there is nothing special at apples products, since HSUPA [High Speed Uplink Packet Access] is hardly adopted by mobile vendors.

Yes, but hardly worth the time to clarify considering the ignorant use of profanity from the original poster, hence I didn't bother to reply. Apple would never add HSUPA to the iPhone before it has been formally adopted and used in numbers by mobile networks -- especially since they are rolling out a new iPhone once a year. Adding (currently) near-useless hardware that would raise the overall price of the device would be silly & affect their competition with other smart phone devices. I'd be curious to know what (if any) competing products have already adopted HSUPA (that are currently shipping). Regards, -elc.

I see where your coming from, but like I said there is a world outside America whos networks already support those faster download speeds, so it would not be adding a useless feature for the majority of iPhone users that live abroad. Plus Sprint and Verizons CDMA networks (i think thats what theyre called) and phones with those CDMA chips already support those downstream speeds (if om not mistaken). Saying that not including it in the 3Gs because a new phone is coming out in a year is exactly the reason we waited 2 years for copy/paste. Additionally, HAVING that feature WOULD make the iPhone more competitive against other phones, especially for the business/enterprise users

"already support those faster *upload* speeds" "already support those *upstream* (if om not mistaken)" Sorry i miss-tryped...and i was referring to upload speeds in the original post...hence me talking abput upload video and streaming live vid from your phone

and that my friend is what u miss. there are very FEW phone that support HSUPA and much less i dont think att, supports it on their network, seeing as they dont even have HSPDPA support setup yet. sprint nor verizon have high speed upload on their EV-DO network either. lets jump across the pond. only a few services support this. and after everything, apple is expected to have an LTE 4G based phone in its next iteration of the iphone. which will double the upload speeds of the overall network. also there are no live streaming apps in the app store. its not an API call that has supported in this latest SDK, giving access to live video. You Cant do it. so the only uploading u'd be doing on ur iphone comes from either ur 1-5 minute you tube videos, which upload just fine now, and any tethering u do, which, if u've ever used roadrunner, is right around the same 3-400Kbps upload stream. (actually i just tested my roadrunner turbo upload speed and i got about 650Kbps) big whoop! wheres the story? why should i be able to upload faster on my phone than my macbook pro? sheesh

Seriously, name *THREE* networks anywhere in the world that currently support HSUPA. I think this is a matter of "having to be right" and "never backing down" vs. being supported by any real facts.

Enrico - July 10, 2009 at 7:54pm

...I should clarify by saying "supporting HSUPA with speeds above 384kbps).

Just off the top of my head Telstra's NextG network in Australia. Also Vodafone UK offers it. Im not gonna sit here and look up companies and see which ones offer that speed so google it https://en.wikipedia.org/wiki/List_of_HSUPA_networks
