Get z4root, and use that, as Universal Androot didn't work for me.
Then download and install Busy Box from the market or link below.
Then get SystemApp Remover by Danesh from the market (This cost 63p, theres prob a free one but I choose this and it worked)
Then go to SystemApp Remover and delete the unwanted apps they uninstall and it saves memory on the phone!
Root phone with z4root, then delete with SystemApp Remover.
I recommend this to anyone who doesnt understand ROMs, flashing and those kind of things and anyone who wants to de-brand it from T-Mobile.
I've put it up on my blog as well with links to files and the applications, please visit...
