TrustedReviews looked at the T-Mobile Sidekick 3
The Sidekick 3, like its predecessor, is a sizeable beast at 130mm x 59mm x 22mm, and it isn’t light at 182g. It does though, manage to incorporate a screen and QWERTY keyboard both of which are larger than you’d usually find on a mobile.T-Mobile Sidekick 3 Review
The Sidekick 3 can be held like an ordinary phone when you are on a call, but for other non-voice phone purposes it is designed to be held length ways. When you extract it from your pocket or the protective pouch that comes with it, the Sidekick 3 looks rather like a handheld games console.
