Well, I've been using v7 for a while and I have to say I'm pretty happy with it.
Better battery life!
Specs are default, using the phone normally (but not that much). The average is 2 days depending on the use.
Max Freq: 1000
Min Freq: 300
Voltage: 0
Governor: smartass2
Also I got to say that the video camera seems better (less breaks), and the performance is good enough although is much less smoother than v6.39.
The GPS doesn't work sometimes (can't find the Satellite), and sometimes I click the power button and nothing happens, so I have to click two or three times to turn on/off the screen. Also it takes a bit longer than v6.39. The buttons on the task bar (wi-fi, 3G, bluetooth, etc) also take a little while to "light up", which means sometimes I click twice and end up disconnecting instead of connecting.
These are just minor things I've found since I'm using this ROM since it was released. Other than that, it's working pretty good, and again I don't think my phone had a better battery life
ever!
Thank you so much Huexxx, and I hope this post is useful
PS: I got 2 SoD during this time.
