Yea...I don't see this iPad version either...
Interestingly enough.. GV Connect just got released as a "native" iPad version of their GV app. Just downloaded it (yes it costs $2.99), and it works like a charm.. Much more full-featured than a Google's app.
Only drawback is that it does't do Push, but if you use Boxcar like I do - you can have it redirect to GV Connect.. So not much of an issue.
Unless Google releases a real iPad app, this one is a keeper:
