I tried to import the passwords from 3.7.2 but it goes in an endless loop which results in no data transfer.
I did a manual backup to my desktop so I have the file there.
I tried using DropBox but I cannot connect 3.7.2 to dropbox any longer.
I tried using the advice for 3.7.1 with iTunes by loading the backup file (renamed, as instructed), syncing my phone, etc, but the data still did not load. It did say "unlock?" and then I clicked Unlock but nothing happened.
Is there any option left besides hand entering all of my passwords?
