Do you know if the black (red accent) version will eventually be released on T-Mobile?
Edit: Ah, missed that this question was asked a page or so ago. My apologies.
I'm having this exact issue as well. Very frustrating, but happy to know I'm not alone. I will try to substitute the Yahoo mail app until the problem is resolved.
Have you tried the downgrade/root method over on the XDA forum? I read many users have been successful following this guide. I believe Setherio is the OP.
I'm running CyanogenMod 7.1 and it has the CRT animations. I heard that this was left out of the "official" leak, but I'm unclear whether it's in the final 2.3.4 update... I would highly recommend downgrading and rooting. Check XDA for the guide. ;)
