O2 have a leaflet in store with loads of bargains. The iPod shuffle is obviously the best, but as far as savings go this caught my eye. Cheapest elsewhere I could find was just over £40. This is currently selling for £31.80, was £50
Mount the light-weight LG HFB-500 Solar Powered Bluetooth Car Kit to your windscreen and you're good to go... and to talk. Holding enough charge for 16 hours of talk time, the kit obtains 1 hour of talk time for every 2 hours of exposure. Plastic clasps and suction cups keep the HFB-500 angled at the sun so you can careen around corners without losing light. When fully charged, the HFB-500 provides a massive 960 minutes of talk time. However, this can be improved - when it is in constant sunlight, the device will provide unlimited talk time.
