Hotspot Shield for the iPhone is free to try and after a week you can chose to pay per month ($0.99) or for a whole year ($9.99). Your money will get you a secure (encrypted) VPN connection to a proxy server in the US. This means all data send via public hotspots (like e-mails and passwords) is secure. Plus you can sneak past geo-blocking websites and iPhone apps to access US-only content outside the United States. Hey, there’s a Mac version as well!
