The Raspberry Pi Foundation has released a new lower-power, smaller, and amazingly cheaper Raspberry Pi version called the Raspberry Pi Model A+. The model retails for $20.

A slightly more detailed analysis of the board can be found at Raspi Today with information on exact weight, dimensions, and power consumption.

When an iPhone user send an text to another iPhone user, Apple quietly pipes the message through their own servers instead of over the traditional SMS network. This feature was originally intended to help avoid per-text charges for people on budget cell plans and is normally seamless - the only user-visible difference is that your chat bubbles are blue instead of green. However, if you switch your phone from an iOS device to an Android device, all future messages from iPhone users get lost in the nether - there simply wasn't a method to disable iMessage from your phone number.

Until now. Users stuck in this situation can now use this web tool to escape from iMessage oblivion.
