well I don't make it such a hard rule, but definitely use some common sense. In general, when I'm not on my home or work wifi (where I know no one is monitoring), I'll avoid going to sites that require me to log in.
If I'm just googling or surfing, there's very little risk from using an unsecured wifi connection via a phone.
The concern with open wifi hotspots is that someone can sniff your packets. So if you're reading email, those email messages can be intercepted. If you log in, your user/pass can be seen. With a rooted Android and some advanced tinkering, you can do everything through a secure pipe, either via VPN or a clever port forward for SSH tunneling.
When in doubt, assume someone can see everything you're doing.
