PLEASE HELP!!! I got sims about a week ago on my iPhone and I'm up to level 23 with 11 sims, my town is worth $600,000 and I've got $1m, yet it won't let me build any businesses! The only icon I see on empty lots on my map is the person with a plus sign next to it? It gave me a hairdresser a while ago but other than that I can't get anything. Help please!!!
