It's still Q1 2012. But even if it's missed by a few weeks, they still won't charge you extra for the update .
Also keep in mind:
- It was HTC, not T-Mobile that said you'd have an update in Q1. Just want to be sure you're not assuming the wrong party.
- The announcement of Q1 by HTC, was not a "promise" but a target.
- Delays usually involve ensuring quality. So don't take a delay if such occurs as a bad thing.
To avoid confusion, there are four different Sensation devices (only one from T-Mobile). HTC could be referencing any one of these when they mention ICS. The roll out could also be different for any of those:
- Sensation (European)
- Sensation 4G (Tmobile version)
- Sensation XE (Beats Audio
- Sensation XL (Extra Large Screen)
josiahw, In February HTC made an "end of March" announcement which mentioned the "Sensation 4G" specifically by its full unique name.
More recently, on March 13th they posted:
As for timing, we’re in the early stages of rolling out Android 4.0 for the HTC Sensation and HTC Sensation XE and upgrades will be more widely available in the next few weeks. The update for the HTC Sensation 4G and HTC Sensation XL will follow. Please note, once we start pushing out updates it will take time for all carriers in each country to get the update. We are working closely with our carrier partners to nail down update schedules for our other smartphones and will have more to share very soon.
I'm skeptical about the upgrade. I had an HTC Aria and back in the day everyone witht the Aria were looking forward to getting Froyo. When I finally got it, my Aria is actually runs slower. My concern is will the Sensation 4G fast enough for ICS? I like my Sensation just fine for now and I will be very disappointed if it run slower with ICS.
