So, you want to buy your girlfriend a phone. Here's how it works: there are girls who like pink phones, and girls who don't. And then there are girls who say they don't like pink phones, but secretly they do. You don't want to go there. Bottom line: if your girlfriend stops you outside one of the mobile phone shops, points to one of the phones on this page and says, "Wow, isn't that amazing (or pretty, or cute)," you're on safe ground. If she says, "Blimey, isn't that pink," stick with roses, chocolates and expensive jewellery.
Once you're sure about the pink thing, there's a plethora of phones to choose from. The sassiest option is the Razr V3, which combines slim lines with a shocking pink exterior. Look for matching accessories, including Motorola's H500 headset in hot pink. LG's U880 is a more saccharine shade, but does support 3G, making it suitable for romantic video calls. The LG C3300 was launched in a relatively restrained maroon (aka 'dark pink'), but now comes in pale pink as well. Both versions loiter on the edges of the pink phone spectrum rather than whole-heartedly embracing the concept -- so if your girlfriend thinks you lack commitment, steer clear. For the complete pink experience, look instead to the Siemens CL75 Poppy, a pink phone with a pink flower on the front and a dangly heart-shaped charm with a pink Swarovski crystal.
Other choices include the Samsung SGH-E530, which comes in lavender pink. If your girlfriend can get past the female-specific 'lifestyle' software, it's one of the better specified girlphones, with a megapixel camera and MP3 playback. T-Mobile also has a pink version of the recently released Nokia 6111.
