Android 2.3 cellphone for $99 w/ $19/mo plan
http://www.mobilemag.com/2011/11/08/republic-wireless-19month-unlimited-plan-has-soft-caps details a $19/mo cellphone plan for a $199 Android cellphhone ($99 w/ the discount code “welcome19″) running version 2.3 aka 'Ice Cream". This depends on using WiFi to talk most of the time, with 'soft' limits of 550 minutes, 150 texts, and 300MB of data which you should not exceed when you're on 3G cellular; no limits apply when you're on WiFi. The phone is basic but decent, and if most of your time is spent inside where there's WiFi, it's an intriguing deal.
