I have an iphone 4 on straight talk and want to edit the mms apn settings. I know I can jailbreak and use tetherme to do this. I'm not averse to jailbreaking, I just don't really need/want any other tweaks right now and would like to avoid the $5 for the simple task of editing the mms apn. Plus if I'm going to jailbreak, I'd like to wait until an untethered option is available. Anyway I've been reading a bit on Iphone Configuration Utility and it seems I can just use that to enter in apn settings manually...I just wanted to double check with the forum: in theory, I can use this and manually enter the straight talk att/mnvo settings for data (the same settings unlockit gives), and also the appropriate mms settings, and be good to go...right? EDIT: Hmm, on further inspection it seems this only allows you to change the main apn settings (for data) but not the mms settings....anyone?
