Possibilities?

Hi,

someone gave me an old BB7730 Wireless handheld.
v4.0.0.188
It has an O2 theme. I've put in the SIM card from my carrier and I can make/receive phonecalls, send/recieve SMS. No internet connection.

Does anyone know:
- how I can change the theme? I've installed the Plazmic theme reader and themes from blackberrygoodies
They're under applications, but not under Themes :confused:
- if I can upgrade the OS?
- how I can install a new wallpaper without a connection to the internet on the device?

Thx!

What carrier are you on, and if you are not on O2 you have to unlock the phone.
