I decided to drop over to the PocketPuTTY website to see if any updates had been made, and there's a huge improvement! I haven't had a chance to play with it much but port forwarding and session saving have been added since the last time I saw it. Hopefully now I'll be able to tunnel home and use my proxy server for a more secure experience when using someone else's network.
New Release Announcement
Edit: this might belong in the apps forum, please move if so and sorry for the trouble.
