Samsung earlier this week shared its Ice Cream Sandwich upgrade list for devices on the four major U.S. carriers, and while products on AT&T, Sprint and Verizon were list, Samsung had no details to share about updates for T-Mobile devices. The good news is that a new leaked document sent to our pals at TmoNews has changed that, offering information on when Android 4.0 may hit the Galaxy S II as well as the HTC Sensation 4G and Amaze 4G. As you can see in the calendar above, the Galaxy S II's update is first, with a tentative arrival date of May 14th. A little over a month later on June 16th, both Sensation 4G and Amaze 4G owners may be getting their taste of ICS.

That's not all of the info that the leaked calendar has to share, though. The document also mentions the names of several new T-Mobile handsets that are scheduled to hit in the next few months, including devices from Huawei and Samsung. Here's how things break down:

• May 9th: Huawei Astro, which TmoNews describes as a "low-end handset"
• July 11th: Huawei Phoenix (full-touch new myTouch), Huawei Buddy (new myTouch with QWERTY), new color of Samsung Gravity TXT
• August 1st: Samsung Cacao, model number "T159" suggests low-end
• August 15th: Samsung Apex Q, which is still a mystery

So there you are, T-Mobilers. After Samsung's silence on ICS updates and the news that the Sensation's upgrade wouldn't be coming this month, it's nice to get an idea of when both handsets (as well as the Amaze) may be bumped up to Android 4.0. Of course, it's worth mentioning that leaked upgrade dates like these can change. If you've got a Galaxy S II, Sensation or Amaze, though, this news is a nice way to help kick your weekend off. Stay tuned for more on these upgrades and new devices as we get it!
