It’s been less than 24 hours since Apple started seeding iOS 4.3 Beta to developers and we’ve already found out many new features the new OS brings, but news doesn’t stop there.

The eagle-eyed folks over at Engadget have made another interesting discovery. Within the iOS 4.3 Beta code there are references to two new iPhone models and three new iPad models. The model names that appear include iPhone (4,1 and 4,2) and iPad (2,1, 2,2, and 2,3)…

The iPad models listed in the code are most likely the upcoming iPad 2 WiFi only, iPad 2 with AT&T 3G, and iPad 2 CDMA variant. Things get a little trickier with the iPhone models. The new models referenced, iPhone 4,1 and iPhone 4,2 are probably the GSM iPhone 5 and the CDMA iPhone 5.

That still leaves the iPhone 3,3. Could this be the rumored Sprint/T-Mobile iPhone 4?

Let the rumors begin!
