The T-Mobile crowd were understandably disappointed when they learned the Ice Cream Sandwich update for the HTC Sensation 4G wouldn't happen in April. Considering the fact that Sensation models were the first HTC devices to receive the upgrade, it's a real punch to the gut knowing several other devices are passing it by. T-Mobile isn't giving us any potential release windows, but an internal document obtained by Tmo News gives specific launch dates for ICS on three smartphones.
The phones in question is the HTC Sensation 4G, HTC Amaze 4G and the Samsung Galaxy S II. Both the Sensation and the Amaze are scheduled to get ICS on June 16, and the Galaxy S II update may hit on May 14.
It's not a good idea to expect these dates to be solid because T-Mobile obviously has issues when it comes to getting ICS updates out in a timely manner. All we can do is hope there aren't any more delays.
