LG Optimus 3D (a.k.a. AT&T Thrill 3D)AT&T’s “first dual-core, dual-channel RAM processor” smartphone targeted at mobile entertainment fans is set for release this Sunday, September 4. AT&T confirmed on Facebook yesterday that the LG Thrill 4G will be available for US$100 starting on Sunday.

Here’s AT&T’s post on Facebook:

Our world is in 3D and your smartphone is your world. Starting Sunday, September 4, your smartphone can be in 3D, with the new LG Thrill 4G with glasses-free 3D for just $99.99. Tell us what you’d do first with a 3D camera! http://social.att.com/otl

The LG Thrill 4G’s release date on AT&T has been moved several times, owing to “a launch delay from AT&T.” But, now that release is imminent, people can start counting down to September 4 for the release of the U.S. version of the LG Optimus 3D launched in Europe.

The stereoscopic Android smartphone has these specs:

  • 1.0-GHz dual-core Texas Instruments OMAP 4430 processor
  • 4.3-inch LCD (glasses-free 3D display) touchscreen
  • 5-megapixel dual-lens primary camera (with 720p HD-quality video capture)
  • 1.3-megapixel front camera
  • Android 2.2.2 Froyo (with upgrade to Gingerbread coming up)
  • YouTube integration

Sprint has a similarly spec’d device with stereoscopic display capabilities: the HTC EVO 3D.

Between the two, which one seems to provide the best potential for an exhilarating glasses-free 3D experience?
