I only tried doing it because of this Consumerist article: http://consumerist.com/5358089/mms-for-iphone-rollout-begins-2-weeks-early - I'm on 3.0 (yes, 3.0, not 3.0.1 or 3.1) on an iPhone 3G - I'm using the benm hack for tethering. - I'm on carrier 4.0 (so everyone that thought it would work only with a carrier update, you're wrong) - I live in the Los Angeles area. - On a unlimited family texting plan. - No text from AT&T, only tested it last night due to the Consumerist article. - Test pic was a lame pic of my macbook =p but it works perfectly I'm so happy! Finally!
