Today I made a backup of my cellphone data
First I found PhoneBackup but is only for windows
After install it on a Windows VM and run it, said that my phone was not tested.
I started the backup and this had fail when started WAP backup but other data (contacts, sms and calendar) was good
Some interesting thing is how SMS are coded. The file generated is in XML and had this structure:
<SMS>
<Number value=1/>
<Storage value=1/>
