IPhone 3G network performance issues aren't isolated to the United States, and the time has come to collect global data. IPhone 3G owners from around the world: Wired.com needs your help. We've created an interactive ZeeMap, and we'd like you to report your iPhone 3G's 3G and EDGE download and upload speeds. We promise it's easy, and assuming your connections aren't grindingly slow, this should only take you about five minutes.

Here's what we'd like you to do:

1. Make sure iPhone Wi-Fi is turned OFF (Settings–>Wi-Fi–>OFF).

2. Make sure iPhone's 3G is turned ON. (Settings –> General –> Networks –> 3G –> ON).

3. On your iPhone 3G, point your browser to TestMyiPhone.com and tap Start Test.

4. Under Download Speed Test, tap the 3G button. After the test runs, record the speed in Kbps (in the screenshot example, that's 171 Kbps).

5. Repeat step 4 for 3G upload speed.

6. Turn off 3G on the iPhone. (Settings –> Networks –> 3G –> OFF). Now, on TestMyiPhone.com, tap EDGE for both the download and upload tests and record your data .

7. Scroll up to our Zeemap at the top of this post. Click "Add." Fill in the Location and Detail fields (see screenshots for examples).

When you're done, your addition should look something like this:

And that's all there is to it. We'll provide an update with averaged global data once we've received a sufficient number of contributions.

Good to go? Ladies and gentlemen – start up your iPhones.
