I have a locked iPad and am going to Mexico for a week. 1) Can I purchase a US VPN (like AceVPN or StrongVPN) to stream Zumocast from my laptop at home? 2) Is using a US VPN a way just to access blocked US sites and/or to do so without signing up for an international data plan? 3) Will I still need to upgrade to an international plan to avoid roaming charges or can I just use Wifi? My thoughts were that I could use wifi and install Skype on my iphone 4g to make calls home. Then use VPN over wifi to access streaming video.
