The iPhone Blog reports that in the iPhone 3.0 beta firmware, users are being warned that they may not redownload previously purchased applications over-the-air without being charged. However, the dialog box (shown below) does indicate that users may still redownload applications for free through their computer.

This is a big move from how things currently work. In the current versions of the iPhone and iPod Touch, users are allowed to re-download previously purchased applications without being charged again on both over-the-air and on their computers.

From months of using the iPhone 3.0 beta firmware, I can not say I’ve seen the dialog box shown above. One of my favorite things about the iPhone (or iPod Touch for that matter) is If I ever need FTP On The Go, or any other app, and I don’t have it on my iPhone for whatever reason, I have the ability re-download it without being charged. If Apple does decide to start charging to re-download applications over-the-air it’ll be a big disappointment. What do you guys think? Let us know in the comments!
