Backup your mobile data
Get a backup of your mobile data and get instant online access to your mobile’s contacts and calendar with ZYB
ZYB is a free service that allows you to make a backup of your mobile data, allowing you to replace easily your contacts when you loose your mobile phone. The use is really simple, you select your cell phone, you put your number and receive some synchronization data and in two minutes the whole process is finished. I found this really useful.
