I also have an LG Rumor and i also get the error 67 whenever I try to send pictures via picture mail or whenI try to access the internet. Also when i get pictures sent to my phone they dont show up in my picture mail inbox but only in my picture mail account on sprint.com. Any help would be great.
do what i did. log onto your sprint account, go to settings and passwords, update your web username and password. wait a few hours, then go to settings>more...>data>update data profile.
if that doesn't work, then keep trying...i had to update mine on my own like 3 times, but it worked quicker than calling sprint about it. trust me. i called more than once a day for a week, and they gave me all kinds of retarded solutions that didn't work. finally i figured out that for some reason, when you update your RUMORs phone number, it doesn't update your data for web use, and i when i went to settings>phone information>version i saw that under username, was my old username from an old number (anyone who used to have a VGA-1000 or a phone of the like will remember using the web on that phone....how it'll say "connecting as firstname.lastname@example.org" on a yellow screen. and i remember my username from having to see that all the time. but i finally realized that having a new number, i should have a new username too, and i figured out that thats why my phone was confused. it was logging on under my new number, but under a username that the number didn't recognize. or something like that.
just TRY updating our password and username through sprint.com.
and if that doesn't work either...
just forget about it. get a new phone or get used to not using the web.
