UK regulator Ofcom says that those in rural areas of the United Kingdom are better off sticking with older 2G feature/entry-level phones instead of newer smartphones like Apple's iPhone and Android-powered phones.
The reason is that while newer smartphones offer greater features, the older 2G phones have better voice connectivity in rural areas. This is likely the result of less complex cellular radios that connect only on 2G and don't have to switch between 2G and 3G signals.
Looks like those original iPhones laying around suddenly got a little more useful for those who live or travel in rural areas.
