howdy! i am a current pc owner and android user considering an iphone 4. but i have concerns... not thrilled about relying on itunes for sync, bummed about proprietary cables for said syncing, and well, it's a new OS that i'm not used to. i was considering the thunderbolt but i am getting wary of the delays and proposed pricing. not thrilled with the screen size of the iphone but i could make do. also concerned about getting a phone that is due to be replaced in a matter of months. any words of wisdom? especially from those who are or were in a similar boat...
