I have my iPhone 4, that admittedly, I have epically messed with the underlying file system on. I'm trying to figure out what would cause an MMS to get to the very end of 'sending' and then fail a few minutes later. At the same time any changes I have made I have always backed up and restored (my day job is as a sysadmin, so I have a pretty good idea what I'm doing). The only outstanding change is the ultrasn0w unlock, which I don't actually need. I do notice it now gives my AT&T 3G, AT&T and AT&T under the new carrier menu. Only the 3G works. Any ideas, or will I probably just be stuck with a restore.
