PalmSMS and the MMS Hack

[MountainDew]

Alright so this is a weird question, I'm using PalmSMS and I notice that it has a feature to send picture messages, but i have gotten a message that when I try to send a message that it's an unsupported format. I did a hard reset and before installing the MMS Hack and/or the palmSMS I wanna know if theres a way to fix the palmSMS picture feature or just go ahead and install the MMS Hack.

Another question is the MMS Hack has both, VZW and Sprint configuration, any hacks to remove que VZW configuration and just keep the sprint one?
