Aircell have teamed up with T-Mobile in the US to offer HTC HD2 users on the network free inflight Wi-fi for up to six months.

The deal lets you hook up to Gogo Inflight Internet services across the US free of charge. The deal started yesterday (March 24) and will go on to June 30 2011 where if you leave it too late to sign up then you wont get the full six months. However, there’s a good 15 months between now and the deadline allowing you to sign up for the six months of service.

Once the service is activated you’ll be able to take your HTC HD2 on flight and download email, surf the web and connect with friends over social media networks all while flying with some reporting the service being as quick as a broadband connection on the ground.

“Aircell is constantly striving to partner with companies that can enrich the inflight experience,” said Aircell President and CEO Michael Small. “With the newest smartphone from T-Mobile, we can provide our customers with a simple, yet powerful way to stay connected, even at 35,000 feet.”

Aircell commented that 30% of Gogo Inflight WiFi utilise the service via a mobile phone rather than a laptop.

After the offer ends normal prices will be charged if you want to continue using the service which is $4.95 per session. The inflight service has become more available recently and now is active on 760 commercial aircraft covering around 2,600 flights per day. The service is being added to more flights continually.
