Hello. I've had my iPhone 4 since yesterday and love it. I haven't been able to use voicemail or MMS. I waited til today then contacted AT&T. I found that voicemail didn't work because I had Cellular Data disabled. MMS still doesn't work though and the rep told me that this is a known issue with 4.0.1 that Apple will be addressing soon. When I try to send a picture message, it hangs at about 90%. Has anyone else had this problem? I've reset the phone, reset network settings and tried on both 3G and Edge to no avail. Searching around I didn't see any thing related to MMS and 4.0.1. Maybe its something else?
