well I did download the Yahoo! one and it completely removed application. i called t-mobile and they say its cuz i need the web. ironically i just logged into windows live today, so i think they're tryin to sell me the service.
the bb department sent me service books, and im still unable to log into aim and yahoo.
and i did register my phone. and im somewhat of a new customer. i had the pearl 8 months ago for about a few weeks..
also, my wifi wont let me browse the web. lol.. yeah 😳
