Qik has beefed up their iPhone app, while not changing the price (free). Qik for iPhone 3GS allows you to pull videos right from your Camera Roll and upload them to your Qik account. The uploading begins automatically, the moment you stop recording. You can shoot in your choice of portrait or landscape mode, and even share your location while streaming live video. (Currently, this only works over Wi-Fi, but Qik has submitted an update to the App Store with true 3G network support.) And once your video's up on Qik, you can blog/social-network it to your heart's content.
[Available from the App Store]
