Upgraded from A2.1 to A3.5 last night, used it for about 3 hours.
1) WIFI on WPA is more stable, re-connects after wakeup/power on
2) Tried Shadow gun, Plants vs Zombie HD, Dolphin HD browser, Need for speed
hot pursuit HD, Fruit Ninjar HD etc. All works fine.
3) MyBook66's 小说下载阅读器 Android v1.3 is not compatible with Alpha 3.0
or A3.5. Messed up background and ghosting effect on rendering makes this
APP unusable. Works fine on A2.1
I found AA 小说下载阅读器 to be an adequate replacement, so I'll stick to
Alpha 3.5 for the time being. Waiting for CM9 ICS or MIUI Beta ROM.
