Netflix

Looks like mSpot has beaten Netflix to the punch. mSpot Mobile Movies will stream movie rentals to your iPhone or any of 30 compatible mobile devices. The movies are delivered over Wi-Fi or 3G connections on demand.

To test your mobile device for compatibility, mSpot sends a text message with a link to the service (iPhone users can enter the URL directly into Safari). Movie Club members can purchase credits that expire at the end of the month if unused. A more expensive option is a one-time rental of $4.99. The movie can be watched for 24-48 hours depending on the film.

Sure we've seen iPhone apps in the App Store that let us change our Netflix queue on the go. These are useful when someone brings up a movie you'd like to see, or you can't remember the details about that DVD you have sitting next to your TV.

How many times have you wanted to actually watch movies on your instant queue? Although the iPhone suffers from a small screen and non-removable battery, there are situations where you'd want to show a clip to a friend or even watch a whole film.
