i have found how to attach files
k .. got the cab's
the first one you need to run is the remove picturemail - this will remove any pre existing picturemail included in the rom
Then soft reset
Then install Sprint Arcsoft MMS (its the same MMS as in this ROM but allows to send bigger files)
After install soft reset your phone again
Good to go
Remove PictureMail & Arcsoft.cab
Sprint Arcsoft MMS 5.2.1.22.cab
