I've used the unrevoked3 auto-root program to gain Superuser access to my phone, but I've been having trouble finding ROMs that work!
I tried using ROM Manager to download/install Cyanogenmod, but it fails every time :(
Has anybody got any ideas/suggestions for me? I'd love to stay on a virgin-copy of Android 2.2, but I'm well & truly sick of seeing the "Low memory" message!! :(
