Maybe it's just me (a TMo BB Curve without an extra installed memory card operating with a good to very good EDGE Signal). But, i installed the software on my BB and immediately after the install, my BB REALLY SLOWED DOWN down to a CRAWL.

When I ran the app, there was significant lag between keypad entries of my GVoice/Google ID and password and the keystrokes appearing on the screen. Once i completely entered my GVoice/Google ID and password and clicked/selected "Login" or "Next" (or whatever) in the app (presumably to login to my account) my BB froze. Had to pull the battery out to get it to unfreeze and restart.

I deleted the app shortly thereafter. I'm still feeling out GVoice so such immediate access via a BB app is really not an essential for me, for now.
