AT&T's fall line-up of smartphones got a boost today with the Motorola Atrix 2 going on sale for $99.99 with a 2-year contract.

However, if you are a new customer signing up for a 2-year contract, we would strongly recommend heading to AmazonWireless and picking up the device for only $49.99.

Unfortunately, the deal isn't so great for current customers as they will have to pay $199.99 for the handset.

Those who already have an AT&T contract may be feeling left out by Amazon's lack of a discount, but fear not as Best Buy is offering the Atrix 2 for $49.99 to ALL its customers, regardless of whether they are upgrading or signing up for a new line.

In case you want to know, the Atrix 2 has the following specs:

  • 4G HSPA+ 21 Mbps (Category 14) connectivity
  • 1 GHz dual-core processor
  • 8 GB ROM, 1 GB RAM, 2 GB microSD card (expandable to 32GB)
  • Android 2.3 (Gingerbread)
  • 4.3-inch qHD screen 960x540TFT, with more than 500,000 pixels for sharper, clearer display
  • 8 MP camera and LED flash
  • Front-facing camera
  • 1080p HD video capture, 30 frames per second playback
  • On Device Encryption (ODE) and Enhanced Exchange ActiveSync (EAS)
  • IPsec VPN
  • Optional Lapdock 100 Accessory

The Motorola Artix 2 is a worthy successor to the original Atrix and if you aren't on AT&T already, $49.99 is a great price for a solid Android phone.
