if you want to stay with Android 2.3 then downgrade to .42 -> root with SuperOneClick -> update OTA to .62 so your .62 will remain rooted

Thank. uliwooly

if next month sony release ROM v.4.0.4 not OTA

.42 can OTA update to .62 or can update to ROM v.4.0.4 at Computer Only ?

[Uliwooly]

I would think they will release it like 4.0.3 for the Arc S Neo V and Ray that was only through PCC or SUS
