i would consider it a "very" beta build right now. i know the guys Akeo & group aren't fully done porting 2.5 to vga yet, but they are pretty darn close. NRG is having some issues with ringers getting corrupted & therefore your phone wont ring. others are reporting of random lock ups which i experienced also. among other things..
the only problem with all this is, 2.5 is freakin cool!! & we all wanna use it so bad. So we've been putting up with a few known issues in order to have the latest & greatest. Some of us have gone back to manila 2.1 while NRG + Crew gets things ironed out.
you can find this in the ppcgeeks Energy Rom thread in the touch pro cdma forum. The thing with NRGz28 lately, he hasn't been updating the thread title or the changelog so you just have to keep in touch with the thread & check the download link inside the first post. It has many new builds which you otherwise wouldn't be aware of.
