If you're looking for an affordable smartphone from a well known brand and are either on O2, Tesco Mobile or Giff Gaff, you could get a lot worse than the Samsung Galaxy Europa, an Android handset with a lot of sex-appeal.
The smartphone - otherwise known as the i5500 Corby - costs only £39.99 on pay as you go from O2 with a minimum top up value of £7.50 which brings its total cost to £47.49 and you get plenty for your money.
There's a 2.8-inch QVGA capacitive touchscreen - unheard of at this price, a 600MHz SoC, a two megapixel camera, Android OS 2.1 upgradable to Android OS 2.2 with a TouchWiz 3.0 user interface and full access to Android Marketplace, a 1200mAh battery, Swype, the augmented reality app, Layar, GPSWi-Fi, an FM radio with RSS, microUSB and Bluetooth.
Compare that to the HTC Wildfire which costs nearly three times as much. You get a slightly bigger screen but the same resolution, a higher resolution camera but a slower CPU, more RAM but weighing 10 per cent extra.
The Samsung Galaxy Europa is not as good as the Orange San Francisco, but then the latter costs more than twice the amount of Samsung's phone. It is also worth bearing in mind that the Europa can be unlocked for around £15 online.
