so last night after jailbreaking the iphone 4 i noticed that the MMS and Facetime are missing.. yeah, i checked the settings under phone tab but still the facetime menu for on-off is missing. MMS is missing too! this morning i upgraded my itunes to 9.2.1 and upgraded the iPhone 4 as well from 4.0 to 4.0.1! after restoring itunes will ask you if you want to restore on your back-up or as a new iphone 4 something like that. do not go on that step! instead go to your safari on your iphone then do the jailbreaking. i did not use wi-fi. i typed jailbreakme.com and not jailbreakme.modmyi.com after jailbreaking go to settings and find phone tab. you should see now the facetime and turn it on. check also your MMS. you will now see the camera icon on the compose message. hope this will work for you guys having problems with facetime and MMS EDIT: i did this step on my iPad 3G and no still luck..
