got an orange san fran unlocked and on vodafone. i cant send mms messages and when i recieve one i get a link to vodafone/getphoto which ive read means MMS isnt enabled on my phone. i phoned vodafone CS and they said because it isnt a phone on their database i cant have it enabled by them and would need to take it to a vodafone shop. Whys that? isit something i can do myself?
