I missed this phone so much so when one came up cheap I had to have one.

The advice I need is this.

What's the best os to use?

I need to use facebook, maps and email. Normal phone functions too, but like most I would like to be able to install apps via the repositories I used to use. I just don't want to start messing about in the standard os to then find out I need/want another.

Cheers,

Wayne.
