Thanks KenV... I edited the blackberry.alx file prior to upgrading and can now see themes from ATT, Orange, Silver, Telstra, TIM & T-Mobile.
Why do you prefer ATT to Orange? They all look the same to me on the preview screen, other than the background image. I am reluctant to load them all for feer of mucking up the order of icons etc... which probably sounds a bit lazy!
So, do you mind please letting us know what you like/dislike between ATT, Orange, Silver etc?
