Fellow HN readers, in particular @wallflower, were kind enough to review my iPhone app last week. Based on that feedback, I have created a lite version.
Bugbox Lite is available on the App Store: http://itunes.apple.com/us/app/bugbox-for-bugzilla-lite/id349892146?mt=8
I would request any Bugzilla users on HN to check it out. If you need to be in a corporate VPN to access your Bugzilla server, Bugbox works in a VPN.
Thanks!
