So I ent and upgraded to the official Vodaphone 4.5 upgraded on my AT&T 8310. So far so good. Had some slow browser isseues this eve, but it was fine the other day so I'm assuming it is network vs OS issue.

I thought I'd see if CitiMobile added my device yet. Sadly, the 8310 is still not listed. But I did try choosing the AT&T>RIM>8800. And it works!! All is good so now I'm back on with mobile banking. LOVE 4.5.
