So on Friday Apple released an update to the iPhone that patched the exploit/hack we talked about the other day that would let someone gain access to your phone and send messages and control more iPhones. This exploit was for all iPhones, from the original to the iPhone 3G to the iPhone 3Gs.
If you haven't already done so upgrade to the new 3.01 version of the iPhone software so you can avoid becoming a victim of this exploit.
If you have been waiting to upgrade because you are afraid your iPhone will get re-locked don't worry. According to BoyGenius Reports.com it looks like new unlocking software has been released.
