"You have been sent a picture message. View your message at http://www.t-mobilepictures.com"
For months I was annoyed with that. The whole point of receiving MMS (picture) messages is to get a quick glance without having to use your desktop! I finally got tired of it and investigated why I was having this trouble. I use the Blackberry 8700g device with T-Mobile cellular service.
Apparently, I am not the only person frustrated with this. A quick check of the forums at Pinstack.com shows many, many people with the same issue. These are the steps I found to fix this issue.
