So my iPhone 3G is unlocked (on 4.1) and I had to manually type in the APN, MMSC, etc. all under MMS in Cellular Data, which enables me to get picture messaging and also send photos, etc. Does anyone know if I would have to do the same thing on the iOS 5? I heard the unlocked version just came out not too long ago and I am thinking about upgrading to the iPhone 4/iOS 5. Any comments or advice? Thanks!
