My feedback after playing with it since release =)
I am holding at about 32% on the 23xxx sprint version. One thing I noticed is the bottom taskbar glitches alot in this version. it didn't in the last one with the hide taskbar option. This one does it either way. It usually happens when text messaging and then closing the phone. (which I do alot so its a little annoying)
here is my workaround. Text. close kb. push the windows hardware key. Push x in lower right corner. (each text hehe) I can post a pic if you aren't experiencing it.
Also dont know if you caught it earlier, but the documents tab isn't max manilla related. It works in nrg's rom ok. It must be something you did related to the fb tab too?
Other than that everything works sweet. cept ie6 missing flash capability
