I have installed Dropbox and it seems to be running well. Does anyone know how to do a backup to Dropbox. Would like to save all phone settings and data if possible. TIA. Update May 09, 2011 I have managed to get a cell phone backup to Dropbox as follows: [On Xperia X10i, Firmware 2.1-update1, Build 2.1.A.0.435] First create a "Cell Backup" folder in Dropbox. I did this on the PC. [You may have to put a file in this folder before it is updated to the Dropbox system - I just put a small .txt file in it.] On the cell phone Select Backup and restore > Back Up > Add new [Enter a name for the backup file] > Continue ... Now open a file manager [I use ASTRO file manager] and select the directory /sdcard/data/backup. Tap and hold the backup file you want to transfer > tap Send You may get "! Unknown File Type message" - Just tap Send again. Tap "Dropbox" on the Send File menu. Select your "Cell Backup" folder > Then "Send to this folder". That's it. Your backup file should appear in the folder and Dropbox will transfer the update to "the cloud" and to your PC. I am sure there is a simpler way to do this, and your experience may vary P.S. Still haven't had the to courage to actually do a restore operation using the dropbox file... Hope this helps.
