You won't find a Phones 4u store anywhere on Main Street USA, but our United Kingdom readers are probably quite familiar with the mobile-focused retailer. Alas, they might not be seeing them for long. The BBC reports that the company is in administration (similar to bankruptcy) after UK carrier EE decided not to renew its contract with Phones 4u stores on Friday. EE was the last carrier to remain as a partner following Vodafone's exit earlier this month.
