I'd love to see you figure out a way for users to access wifi hotspots that require a login. I'm not sure how this would work since you attempt to authorize mobicip as soon as it launches, but at LEAST see if you can have the browser look for the AT&T wifi access screen when it can't find the internet. Then have it kick back in once the user has achieved internet access through the hotspot. I assume (maybe wrongly) that there's something you could look for that would reveal the page as an AT&T hotspot and you let it through before mobicip actually authorizes itself (since it can't anyway).
This would really take this cool little browser to the next level.
