Although they aren't designed for the purpose you have in mind, anonymizing proxies should work fairly well. I haven't looked into them in years, but anonymizer.com used to be one, and if you just google for anonymous proxy services you should find an assortment.
Keep in mind that you need to trust whoever's at the other end of the connection, or you're wasting your time. Frankly, you're probably better off just focusing on using secure services (i.e. SSL/HTTPS instead of plain text logins, SSH instead of telnet, etc).

Primarily concerned about the security of WiFi/public hotspots. Encrypting those from my device to the terminus somewhere in the US would secure the traffic against attackers eavesdropping over the air, or who may have set up the hotspot for malicious purposes.
