Fly Mobile is the new kid on the UK prepay block. Right now this Blighty-based manufacturer may not be so well known over here but over in Russia it's sold over 1.2 million handsets. Now the outfit is gunning for a share of our prepay market by delivering feature-rich handsets at arctic cold temperatures. Its first handset, the SL500, sold in Argos and Orange (as the TR1) retailed for around £40. This slider packed a 1.3-megapixel snapper, expandable memory and built-in music player. Its successor, the SL600, is even better, arriving loaded with a two-megapixel camera, microSD card slot, built-in music player and FM radio, recordable radio and stereo Bluetooth, all for just £60 on Vodafone from your local Woolworths. It's an impressive line-up for such a minimal outlay. For the low asking price you probably don't think you deserve a nicely designed and made phone but the SL600 is a sleek, incredibly lightweight compact slider that, although feels a little plasticky, is still a well-built handset that belies its entry-level price tag. The spring-assisted slider action is also smooth with a soft glide and all the keys and five-way Dpad are big, bold and welcoming to the fat-fingered fraternity. The SL600's menu system is graphically very reminiscent of Samsung phones and plays out much like the Korean's intuitive user-interface. The SL600 might throw up the odd unexpected operational twist and but it won't take long for you to master. The 176x220 pixel resolution display is also pretty much standard issue for a mid-ranger and does the job. Considering its price tag the SL600, on initial impressions, has exceeded our expectation. Lets hope it can keep in our good books with its multimedia performance, so look out for our review of the SL600i musical talents very soon.
