ok i got my iphone for free as a hand me down and it came with 2.0 installed. im too lazy to downgrade it because i sounds like its a real hardcore ***** to do. so im going to ask the question? when will most or alot of apps be ported to 2.0, and also is it worth the wait or should i downgrade, how hard is downgrading on osx leopard.*whats the easiest way possible

thanks, corey
