if not mistaken, without rooting, cannot remove those programs...u can try under settings>> applications, but most likely cannot.
another dumb question...are there any way (cept rooting) to remove most of the programs I don't use in the phone, e.g. peep/plurk, teeter etc?
i realise that i only have 142 mb of available internal mem left, and I only installed ebuddy, astro, jewellust, and raging thunder....
