Now that Aircell has finished roping every major US airline into its plan for world domination providing inexpensive WiFi on most every flight, the company's dealmakers have had to fall back on, shall we say, less integral partnerships to advance their strategy. First up? If you're the owner of a shiny new HTC HD2 on T-Mobile, you get six months of Gogo in-flight WiFi, free of charge. Simply register with the company anytime before June 2011 and it's clear skies for your connection. You can consider the expiration date a bonus alarm clock -- by that time, you'll be ready for a phone with enough buttons for Windows Phone 7 Series.
