I just purchased this handset before three days.
Initially ithought its not going to support opera or any othe social n/w.
I called service provider 10 time(Stuppid DOCOMO/not DOCOMO but the executives over there, they first of all think to kick of the cutomer out of call telling false reasons)
The problem was very simple, I was missing the settings for JAVA account.
If you have the same model, click menu on first screen you have settings, got o last tab, 1)Data Accounts2)WAP 3)MMS 4)Java.
Select the connection type http, no proxy, then select data account for you SIM(ie. Vodafone GPRS) for me I choose DOCOMO internet.
Thats it, now got ot opera mini and enjoy marvolus web experience on your cell phone.
Please let me know how can I mute the power on/off sound for same model.
