Give me a break
Wow... its very telling to see all the window$ ppl attempting (in vein) to point out how superior their OS is. Just take a deep breath, and realize how stupid it sounds to suggest that OSX is anywhere close to being as insecure as Window$.
The iPhone will get hacked. Then Apple will patch it. Making $300 profit on each unit gives them quite a bit of coin to spend on this process. Also remember that it is running on *NIX foundations = roxing stability/security.
I don't have an iphone & i won't buy one at that price. But given what i've seen I'd take an iPhone over some POS windows mobile device.
