I just upgraded to 5.0.0.900 tonight and it's been a headache since I had problems with the ROM connect issue mentioned elsewhere. Bottom line, while I still have my calendar/contacts data, I lost most everything else like my speed dial and browser bookmarks.

I had the same problem mentioned above and changing the browser from T-Mobile to internet browser did the trick. Yes, when it's the carrier's browser, the use current page button doesn't appear and you can't change it.

Thanks for the solution. This really helped me out.
