The HTC Vision release date is not official by T-Mobile, but we speculate the HTC Vision will have a launch date sometime during the 3rd quarter of this year (2010). Although, we cannot really narrow it down much from here, it has been noted that the HTC Vision and HTC HD3 might be paired as a dual release. So if any information is leaked for the release date for the sister phone, then we should be able to relate that information to the Vision. Stay tuned as we learn more about this SIM based phone from both HTC and T-Mobile.
