—–UPDATE (12/22/09)—–
AT&T has threatened to put a limit on their UNLIMITED data plan to 5GB/month. Heavy tethering users (such as myself) WILL GET DATA OVERAGE CHARGES if this is put into effect. YOU USE TETHERING AT YOUR OWN RISK.
DO NOT UPGRADE YOUR OS! YOU WILL NOT BE ABLE TO DO THIS TETHERING TRICK ON ANY OS OTHER THAN 3.0 AND 3.0.1!
Please read the following before you begin.
This video tutorial will show those who wish to get internet tethering on their iPhone 3G or 3GS with OS version 3.0 and 3.0.1, without having to jailbreak their device. This is a free modification to your iPhone.
Internet tethering enables you to connect your iPhone to your computer/laptop and use the internet connection from AT&T’s 3g network. This allows you to have an internet connection for your laptop anywhere that WiFi is not available, but 3G or EDGE is.
-This DOES NOT give you “free internet.” There is no such thing.
-This DOES NOT add any charges to your phone bill, however it is recommended that you have the unlimited data plan to prevent data overage charges. I am not responsible for extra data charges to your phone bill!
—If you still don’t understand what this modification will do for you, do not attempt.—

Verizon is the only company with good reception in my area, but also happen to get 3G on my blackberry pearl. I just thought i would hook it up and test the connection, It was actually pretty good, you can watch you tube videos in standard quality (barely)
The download speed were not really that bad: 512 Kbps (which is low-end DSL, or something you might expect at a busy airport)
But the upload speeds on the other hand were flat out horrible: a mire 100 Kbps (which would take you about 10 minutes to upload a image taken from a normal digital camera)
The verdict: This is definitely not something your going to want for stream video up to u stream, or uploading anything at all. but surfing the net wasn’t all that bad.
