Few statements can be considered more exciting than the following: Finally, I have a use for bluetooth at home!
OK, I'm lying, but still.... We stumbled across a very simple and satisfying solution to an annoying problem. In our new apartment, we have fairly poor cell reception. Believe it or not, with Verizon, not with AT&T. The phones work, but calls drop pretty regularly if you're not actually near a window.
A friend of ours has AT&T and mentioned buying a microcell to solve that problem -- but that's kind of expensive and it irritates me that I have to pay so much to solve the cell provider's issue. So, here's what we stumbled upon instead: The Cobra PhoneLynx Bluetooth Cell to Home Phone Connection System.
What does it do? It connects to your fancy smartphone over Bluetooth, and then it connects to whatever regular telephones you have. We've got ours connected to a cordless phone system with two phones and two base stations. When we're at home, we drop our iPhones into their chargers, conveniently located by the window, where they get great reception. Then, if a cell phone rings, the house phone rings. The house phone is thus an extension for your iPhone. Since the cell phones remain near the window, reception is always great. And the thing supports two phones/two bluetooth connections. Caller ID tells us if phone #1 or phone #2 is ringing.
Wasn't sure if we'd find this all that useful, but it turned out to be a life-saver that we use every day.
And when you pick up one of the cordless phones, you get a dial tone. Dial like normal, and your call goes out over your cell phone.
