i guess you give this a try.. its supposedly one of the best around

TOR
What is Tor?
Tor is an implementation of version 2 of Onion Routing.
In brief, Onion Routing is a connection-oriented anonymizing communication service. Users choose a source-routed path through a set of nodes, and negotiate a "virtual circuit" through the network, in which each node knows its predecessor and successor, but no others. Traffic flowing down the circuit is unwrapped by a symmetric key at each node, which reveals the downstream node.
Basically Tor provides a distributed network of servers ("onion routers"). Users bounce their tcp streams (web traffic, ftp, ssh, etc) around the routers, and recipients, observers, and even the routers themselves have difficulty tracking the source of the stream.
Individuals can use Tor to keep remote websites from tracking them and their family members. They can also use it to connect to resources such as news sites or instant messaging services that are blocked by their local Internet service providers (ISPs).
Why we need Tor
Using Tor protects you against a common form of Internet surveillance known as "traffic analysis." Traffic analysis can be used to infer who is talking to whom over a public network. Knowing the source and destination of your Internet traffic allows others to track your behavior and interests. This can impact your checkbook if, for example, an e-commerce site uses price discrimination based on your country or institution of origin. It can even threaten your job and physical safety by revealing who and where you are. For example, if you're travelling abroad and you connect to your employer's computers to check or send mail, you can inadvertently reveal your national origin and professional affiliation to anyone observing the network, even if the connection is encrypted.
