[update2] looks like Apple read the blogs and pulled the app… sorry.
[update] I was able to purchase the Handylight app from the app store. Works on iOS4 and the iPhone 4. NO JAILBREAK REQUIRED!
It took a small bit of tweaking to get all of the steps right, but it did work and work well. Here is the speeds I was puling from speedtest.net
[original] It's still in the app store for now. Follow this link to learn more and download. Cost is $.99 no jailbreak necessary.
