Ericsson T28 Mobile Phone

When it arrived in 1997 the Ericsson T28 was the thinnest phone in the world — 83 grams with a lithium-polymer battery and a spring-loaded flip that snapped open with a sound owners still remember. It was the executive handset of the pre-Nokia-dominance era and has aged into a genuine design object. This index tracks original T28 units on the European second-hand market, where clean working examples and boxed stock sit some way apart.
