For anyone that hasn't tried Google Voice yet it is a great application for combining multiple phone numbers into one number for easy communication. It offers a lot of flexibility in how you wish to communicate with people.
Google Voice App was updated recently to v0.1.7. It reminded me to check my notes on how to install it on my Blackberry Storm 2(9550). Before you go to m.google.com/voice to install it. Open your BlackBerry Browser, under Options, then Browser Configuration change Browser Indentification to Firefox and save options. Now open the URL above and it present you with a download and install.
