Ericsson T28 (1999)

Remarkably slim and lightweight, the T28 was the thinnest phone on the market when released. Its distinctive flip design with a spring-loaded mechanism added a sense of sophistication, while the active flip (which could answer and end calls) made it incredibly convenient to use. The T28 was also one of the first phones to feature a vibration alert and a phone book that could store images alongside contacts.
