The Nokia 5140i is an upgraded version of the 5140 & they are both very sport orientated mobile phones. The Nokia 5140i comes with some very useful features - which include a flashlight, compass, thermometer, alarm clock, stopwatch, countdown timer, currency converter & calculator. There are also sports-related wallpapers, animated screensavers and MP3 ringtones. The Nokia 5140i is fine if you just want a tough phone for reckless adventuring. The built in FM radio comes with stereo sound & is perfect for those more relaxing moments. The Nokia 5140i has an automatic key guard which prevents the keys getting knocked & activated. The Nokia Xpress audio messaging feature allows the user to record their voice message. The handset's main selling point, though, is its robustness - it's the type that can survive bar spills and pavement plummets.
