This program works pretty well barring a few issues. I am using it on a nexus one with 2.2 and have a few local(over the local wifi) ftp/sftp hosts set up as well as a remote (over 3G) SFTP set up. I've had a few issues when connecting to SFTP locally over wifi. These issues would occur when a transfer would hang causing AndFTP to force close. I would then be unable to reconnect to the SFTP server. I would continuously receive Java socket errors. The only resolution was to cycle the power on my wireless router. That being said, I'm can't hold those issues against the app. Using it to connect to the same SFTP host remotely over 3G has been rock solid, just a bit slower then the local wifi connection. It really does make transferring music from home to your SD card really convenient when you want to load up some new music for a run or car ride.
