Help Can no longer manually download mms?

[manofsteele37]

Ever since I first purchased my Infuse, I have usually kept my internet network turned off to save battery. I have the option to automatically download mms turned "off" so when I receive a picture message, I can turn on the network and manually download it. For some reason the "download" prompt no longer appears in my stock messaging app or Chomp sms. So theres no way to tell if ive even been sent a picture unless i have the network turned on all the time. If I've been through the network settings for both apps and can't seem to figure it out. Any ideas?
