If you change phones a lot for any reason, you must be familiar with the problem of transferring your contacts.

One way to solve that problem is to regularly backup your files. But this does not have to be limited to just contacts. Other files, such as SMS, pictures and calendar entries, can be backed up too.

If you have a PC, you can backup your phone via whatever PC Suite the manufacturer supports. If not, an online backup service is a viable alternative.

ZYB is an online sysstem that backs up all the contact information on your phone to the internet. ZYB automatically updates your contacts, on the phone and internet, whenever you or your friends change or add information. This basic functionality is free.

Basically, you need a GPRS/EDGE/3G/HSDPA connection, and you can backup and restore your files anywhere, anytime as long as you are within network coverage.

You can also backup your contacts by sending SMS to a predefined number. Picture backups can be done via MMS as well.

The advantage of thee online sservice is that you are not tied to doing backups and restores from just one location (wherever your PC happens to be).

In addition to backing up contacts, ZYB also backs up your calendar entries. You can also backup your SMS, pictures and videos for a small subscription.

In addition, ZYB shows you your frieends’ Social updates from Facebook, Twitter, Flickr, Hyves and blogs.
