A lot of contacts, documents, text messages, games and other data live on your smartphone, but manufacturers and service carriers aren't going out of their way to make backing up easy. Gizmodo, however, has you covered on nearly any platform.
John Herrman runs down the best, easiest and cheapest methods for backing up iPhones, Android units, BlackBerrys, Windows Mobile and Palm smartphones. Some involve backing up right to your computer's hard drive (which you can then back up to an online service or elsewhere), while others drop your data onto SD cards, or onto free or cheap web cloud storage space. Not every platform supports every kind of data backup, but most allow you to put enough aside that a lost, stolen, or memory-wiped phone wouldn't cost you a whole day's worth of re-configuring.
