iPhone 4 international speed tests

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).

Has AT&T fixed HSUPA upload speeds in your area?

A bunch of readers are telling us AT&T and Alcatel Lucent have fixed the issues with HSUPA (high speed uploads) and their iPhone 4's a positively racing up the information superhighway again. Not everyone in every place seems so lucky, however, as our good friend @TCPJ_Mickey, still seems to be chugging along sub-100 in Arizona.

You know what this means, right? Speed test!

iPhone 4 - Faster 3G speeds or nothing but speed bumps?

While iPhone 4 adds 3G HSUPA (high speed uploads) to preview HSDPA 7.2 (high speed downloads) and is giving many users much faster data, others are filling our inboxes with complaints their speeds are so slow they border on 2G EDGE... or worse.

I know when I upgraded my iPhone 3GS to iOS 4 I had some data issues but almost immediately my carrier, Rogers, pushed out an OTA (over the air) Carrier Settings Update, taking it from 7.0 to 7.1. After that, I was flying.

iPhone 3GS Doesn't Support HSUPA for High Speed 3G Upload

Macworld is reporting that while the iPhone 3GS chipset does indeed support the new (for North America!) HSPDA download speed of 7.2 Mbps, Apple didn't see fit to equip it with the matching HSUPA upload speed of 1.4/1.9 Mbps. Indeed, they claim the iPhone 3GS will top out its uploads (sending videos to YouTube, emailing photos, etc.) at a comparatively anemic 384 Kbps.
