Something I didn't make clear last time... the moblog functionality only works if you're sending a photo. A straight text message won't work. The formats of different providers make it tough to really nail down something that will work for everyone, but per normal RFC's, an e-mail attachment (photo) is always the same.
Regardless, the developer of the e-mail component I'm using just put out another build. Maybe this one works better.
You should see all of the crap text sent with photos from Verizon! Every entry would be an ad!
