Here is one for frequent travelers with an iGadget Skype released an app called Skype Wi-Fi, available for all iOS 4.1+ devices (iPhone, iPad, iPod Touch).
What Skype Wi-Fi does is give you access to over a million commercial Wi-Fi hotspots around the world and lets you pay for using them on the go with your Skype Credit. Its good for quick connections to the Internet at odd places, but not so much for all-day usage as you are charged by by the minute.
For example, if you have a layover a some airport and need to check your email Skype Wi-Fi is an easy solution you do not need vouchers or anything, just some Skype Credit. Prices start at $0.06/€0.05 per minute and the app clearly displays how much it costs to use the current hotspot. This weekend (20-21 August) you get an hour of Wi-Fi use for free.
