I reset my phone statistics the other day and I went out and sent an iMessage. I looked at my usage and it was at 2.1MB...and all I did was send an iMessage! I turned off iMessage and have only used txt since then (I have unlimited so why waste data anyway) and I have used 25MB total since then, and I use my phone a lot to go on facebook and web surf. Why would a message that should take, at most half a kb use 2.1MB???
