LG Optimus S is a great little phone
The LG Optimus S is a great phone. I know because it was the first Android phone I used (passed it on to a family member when I got my EVO) and I really enjoyed the little phone's capabilities. Well you can now get the mid level Android for $20 on a two-year contract with Sprint.
LG Optimus S Specs
In case you're wondering, it has a 3.2 inch screen, a 600 MHz processor, a 3.15 mega-pixel camera, and 512 MB of RAM. I highly recommend this one for those of you who don't really care about upgrading in the near future and just want a functional Android phone that does the things you need it to do. Otherwise, I'd say give it a second thought before making the leap. Two years is a long time.
