I'm very interested in using fido for several projects. We just filled up a freezer with beef and it is not in the most accessible location to notice if it is broken. But there is WiFi!
I'm interested in both the raspberry pi as well as the android phone version. The easiest and cheapest for me is the android since I have an old gsm galaxy nexus with screen issues but that runs fine for short periods of screen on time and perfect for screen off. Is the apk available to setup reporting if I buy the 3.5mm headphone thermometer and an extension cord?

First of all, make sure that all the messages on the phone have been erased. Now make sure the Arduino is reset while already plugged into the phone. After a power up, if the light blinks green, then things are fine and you can go ahead and program!
Programming Fido can be done in two text messages.
First, text Fido the default master pin, "#FIDO" - Fido will make you the owner and you will be allowed to program Fido settings.
Building a back-up battery for your Arduino just takes a little bit of soldering! Take a look at the following circuit.
You can find a Motorola C168i on Ebay for less than 10 dollars. The simplest way to get service for it is to buy a pay-as-you-go SIM card, at Radio Shack for example. While you're there you can also pick up the 3/32 plug; unfortunately, they don't have any information on the packaging but I've included a figure here for your reference (see left).
