My wife currently has a Nokia (and E3 I think, from memory) and it's terrible. Really poor OS / interface, not intuitive, just no fun.
I've read great things about the Orange San Fransisco, which comes with Android 2.1 and supposedly a load of Orange rubbish, but is relatively easy to upgrade to plain Android 2.2.
Since it's available to buy for £100 Pay As You Go, i wanted to check that I could simply buy this phone, swap the SIM over, and bingo (her Nokia is with an Orange monthly contract).
Cheers
