In a curiously worded statement, AT&T has claimed it prevented the iPhone version of SlingPlayer from using 3G because it would chew too much data — and because the iPhone is, oddly, not considered a phone

The short message justifies the decision to allow Sling Media’s remote streaming only without 3G use by first noting that a Slingbox consumes a large amount of bandwidth on AT&T’s cellular towers and could “prevent other customers from using the network.”

However, it’s here that the wireless provider’s argument takes an unusual turn. As mentioned by Engadget, AT&T specifically cites its terms of service — which have flip-flopped over the past several weeks — as preventing users from re-routing a TV signal through the 3G connection to a personal computer. But rather than add smartphones to the clause, the

company tries to fit the iPhone into this category by claiming that it’s too powerful to be a regular smartphone.

“Applications like this, which redirect a TV signal to a personal computer, are specifically prohibited under our terms of service,” AT&T claims. “We consider smartphones like the iPhone to be personal computers in that they have the same hardware and software attributes as PCs.”

Instead, the carrier says, iPhone owners should be content to stream Slingbox video when away from home through the free Wi-Fi access they have at certain public locations, such as Starbucks coffee shops. Web video streams are also allowed.

This explains the lack of 3G with the iPhone version of SlingPlayer, but it sounds like AT&T just being afraid of their bandwidth being chewed up, and causing more issues with their service.

SlingPlayer app for iPhone will be available on the App Store on Wednesday morning, according to a Sling spokesman. Unfortunately, since the company advises a 3G connection preferred to enjoy Sling on the go, this version is only working with Wi-Fi connection.

uses an internet media bridge to stream TV or recorded video from a user’s home to any compatible device like mobile phone.

According to Wired.com:

Sling originally submitted its SlingPlayer app, the software had the ability to stream video over the iPhone’s 3G, EDGE and Wi-Fi connections. However, Apple required Sling to modify the app to work with Wi-Fi only, according to Sling.

It’s reported that a 3G-capable SlingPlayer for iPhone would violate AT&T’s terms of service and could potentially strain AT&T’s 3g network. But it’s a bit weird since other AT&T devices like the BlackBerry Bold supports a 3G-capable SlingPlayer app.

The SlingPlayer app will be available for $30 in the App Store between midnight and 6 a.m. ET Wednesday
