Hi guys! So I want to buy an unlocked iPhone. I currently don't have a data plan (and i'm seriously not intending on getting one) and I was just wondering if the iPhone is fully functional without it? So if, for example, i buy one of those jailbroken/unlocked iphones from ebay I can use it normally with just the wi-fi. Like, use applications and check the internet and such. I'm asking because I recently found out that in Blackberry's this isn't the case - you can't use any apps without having a data plan. so yeah. thanks guys!
