Very very good (WP7.romVer2.0).
I am using GoLAuncherEx, no WP7.
No issues found. I checked camera (no FCs), calls, gps, mail, alarm, usb (dual mount) and some of my apps.
Seems to be more responsive than stock b08c, no lags at all.
I didn't wipe/factory settings, flashed over b08c with data and didn't loose any data, my 178 apps still there working ok... just wiped cache & dalvik before install.
