#1 – Carolina – there are other approaches to warnings that can be sent to any phone, and landlines in some cases. The local municipality may have a text message alert, or a phone based alert. Often the local college will have these if the municipality doesn’t. Other than the cost of receiving the text, people should be able to find one with no fee. There is a free service from f5data at http://www.cellwarn.com/ Our local township and our local college also offer services like this, and send a recorded phone message to any phone you choose. Neither of these requires a smart phone.

Here’s another, but I’ve not used this one -

They say they’ll add carriers not currently on their list.

If necessary, on most but not all carriers, you can sign up for an email type alert on your phone, by using the email address for SMS service – the address will be your phone number @ some domain specific for your carrier. This may be a little tricky to authorize properly (they usually want a reply from the address as approval) but it can be done. This is an extreme case, though I know of at least one carrier where even this is not possible.

#2 – Please put something in the article title that indicates what system you are discussing. Everyone doesn’t have (or want) an iPhone. Go Android!

#3 – How about making the word “blog” findable on the radioshack.com page? It is there, but a search on the page doesn’t highlight it. (At least in Firefox.)
