After trying the new RSS channel reader in the new PSP 2.60 firmware, I’ve found it doesn’t support text only feeds. This is a very big dissapointment. It only allows playing of MP3 and ACC (MPEG4) audio files so is not as useful as first thought. Its a nice try Sony, but do a proper job next time not a half arsed job!
It looks like Sony may consider adding text feeds as indicated here: Macworld: News: Sony will consider RSS text feeds for PSP. Come on Sony, do a proper RSS implementation.
