The idea for this app is great, but there are too many problems for me to continue to use it until they are fixed:
1) The app has no exit, so it will always run as a service unless you kill it in a task manager (most new users - about 200,000 a day according to google), won't even know what a task manager is, let alone know how to kill a service.
2) It doesn't allow you to change your status to "busy", "away", etc. It just stays online.
3) I noticed that about half my contacts didn't even show up on the contact list!
4) No options to change the call behavior (i.e. ring type, vibration settings, etc.)
Like I said, great idea, but poorly executed. I'll be keeping an eye on updates though.
