I saw a tweet about still able to use Freegate yesterday. There are a few other similar alternatives that may still be accessible. You need to download a small client like Freegate. Freegate is only free for some countries now.
Ultrasurf is fast, possibly has some US govt fund.
Hotspot Shield is a very fast VPN, ad supported. Both US servers.
JonDo is Europe based, a bit slower, best before UTC 9am, when TOR is just about usable (at my geolocation).
GPass can be used directly or via skype. I heard a lot of middle east telco block skype, but also heard that it's hard to block. All the above are always encrypted.
For simple CGI proxy there's vtunnel.com ctunnel.com and a list at
ctunnel. Working well and ran by the same people. Most proxy can use SSL encryption as option.
There are alternatives to installing a cgi proxy on your computer such as J Marshall's. As above, TOR can be set to operate as a relay with or without exposing your IP as an exit point. But I doubt if it makes a dent on the TOR network. In JonDo, you can allow others to access the service through your client, but I don't know how it works because if you can block JonDo, you can also block it's infoservices(?), which tell others where to look for you.
