My iPhone 4 is getting pretty much the same 3G HSPA speed under iOS 4.1 as it was under 4.0.x, how about you? There was nothing overtly mention in iOS 4.1 that should have changed things, but you never know what gets tuned under the covers, never mind what your carrier is up to in your region.

One of our readers, Paul, swears his speed has tanked by a factor of 10 since the update.

So break out your favorite measuring tool (I used the SpeedTest.net app) and let us know where you are and what your speeds are like.

You know the drill — iPhone 4 just went on sale in 17 additional countries so hit up your favorite speed test (I used the speedtest.net app) and let us know how the new HSUPA (high speed upload) radio is treating you.

(And if you’re in the US and have just gotten yours fixed, let us know how that’s working as well).

What kind of upload and download speeds are you getting on your iPad Wi-Fi + 3G? Apple included an HSPA 7.2 3G radio on the iPad 3G, so if you’re on an HSPA+ 21 network like Bell/Telus you won’t approach that face-peeling velocity, and in the real world where you’re not sitting on top of your own cell tower in a test lab, you probably won’t hit 7.2 either, but we’re curious to know what kind of performance you do get.

So far, on Rogers Canada, I’m getting close to 4mb/s as measured by the SpeedTest.net app [iTunes link], which is pretty much the same as I get on the similarly equipped iPhone 3GS.

Let us know where you are, which carrier you’re on, and what data speed you’re getting.

How fast is your iPad Wi-Fi + 3G on AT&T? Dieter is testing his out and the results so far don’t seem too shabby. We’ve seen the plastic top strip meant to allow better, stronger radio signals and we’ve seen about all the details in the iPad 3G tear down, but real-world results are what matter here so run your favorite speed test, website or app, tell us which one your run, and let us know your results.

TapTapTap, developers of the upcoming Plasma app decided to slap a big, honkin’ frame rate indicator on a raw version just to see what differences, if any, the iPhone 3GS hardware provided compared to the previous generation iPhone 3G. The results?

As the video shows, in our OpenGL ES testing, the 3GS is generally close to four times faster than the 3G. Results will vary depending on the application but this is remarkable to say the least.

Check out the link above to watch the full QuickTime video. Impressive stuff.

TUAW, meanwhile, had this to say:

On a related note, we hear that Apple has done “even more” than we can publicly disclose around speed improvements on the device.

Hmmm, do tell?

Taking my cues from Dieter, I just ran my freshly (and thankfully) activated iPhone 3G through its http://inetworktest.com and this is what I got:

600kbps baby!

Okay, that was the 3rd and highest of 5 sequential attempts. Test 1 and 4 were 405kbps and tests 2 and 5 were 545kbps. Rogers does claim to invest heavily in their network (which they remind us every time we pay the monthly network improvement surcharge!), and 3G pretty much covers the greater Island of Montreal, where I am, so maybe they’re at least putting some of the massive amounts of money we fork over to good use!

Speaking of Rogers, please forgive me making a quick shout-out to everyone who was in the line at Fairview, Pointe-Claire (especially those who are readers of TiPb!), and to the staff who remained friendly, classy, and courteous through Rogers continual plan changes, server crashes, and iTunes activation all leading to me — who was first in line — finally getting out some 3 hours after the store opened! (Next time, tell head office to call up Google for some pipes, b’okay?)
