Just a quick n00b question for anyone who's lurking around tonight, I have my APN settings for my unlocked iPhone 3G shown below. However after comparing my settings with those on my Dad's new 3GS, I noticed that he had considerably more to the Network menu than I did. Also, when I went to sync with iTunes (after successfully evading the 3.1.3 prompt), I had a Carrier Settings update prompt come up. Would updating Carrier Settings allow me more flexibility (ie - with respect to tethering and multimedia messaging) than I would have before? I've poked around a bit online and on this board and from what I can see it is safe to do with an unlocked phone, however, I just wanted to make sure? If it doesn't help, am I able to revert to my original APN settings myself, or do I have to take the phone back in to have the the pda2.bell.ca APN put back into that field on the phone?
