Hi, I want to create a group messaging social network type app for the iphone with locations features similar to something like loopt. I dont have any programming experience but i've been working thru an intro iphone app book and am doing ok so far. i understand this will be pretty difficult, but do any of you have any suggestions for learning materials? I'd love some suggestions for learning everything from the database back end right up to the actual interface of the app. Clarifications regarding big picture setup would be greatly appreciated as well. Thanks a bunch in advance!
