I’ve made a bit more progress on Mobile Scrobbler:
The status bar at the bottom has been replaced with a UIProgressHUD (see the spinny thing in the picture), and the app now puts a music note icon in the status bar indicating it’s running in the background.
It now also has basic error reporting when things go wrong. I also added code to make the iPhone connect to the EDGE network if it isn’t already, so scrobbling should work on EDGE as well as wifi.
I still need to add queuing code for when you’re in an area without signal, and I’m still waiting for last.fm to assign me a client ID. I’m hoping to be able to release MobileScrobbler soon!
