All,
I've seen quite a few posts lately that say Tytung's v2.1/2.0 ROM is not very fast or smooth. To the contrary, I've had a great UI experience with Tytung's ICS rom. Since I have the luxury of owning more than one HD2, and since I kept my Gingerbread version current (just in case I had to "fall back" in the event of something I didn't like in ICS, I figured I'd perform a side-by-side comparison of Tytung's 2.37 GB rom vs his 2.1 ICS rom. As they say, a picture is worth a thousand words.
For the most part, you'll see that GB is slightly quicker, but hardly noticeable. So for those who are experiencing really "slow" performance, it must be something that you're running, or some other config issue, since I've now flashed v2.1 on another HD2 and have also had good results.
Now, if Tytung can figure out a fix for the barcode scanner issue, and possibly a way around TMO's tethering block ;-)
