Amazing
Could potentially be the best program on iTunes. Works 100 times better than normal visual voicemail and its free!
That said, configuring it takes a little bit more work than you would think. In Canada, use *004*accessnumber# to program it on your phone, but your carrier voicemail must be disabled first before it will work. Contact your carrier for this. Tested and working on multiple carriers! Check the YouMail website for help configuring if you cant figure it out. 5 stars!
