Filed under: CellphonesAs if anyone expected it to stay locked down forever, the layers of security surrounding v1.1.1 of the iPhone firmware are being peeled away. TUAW's Erica Sadun managed to get read / write access to the phone's directories during her liveblogging session, and the hackint0sh forums are abuzz about a new hacking method that uses buffer overflow via "carefully crafted" TIFFs that crash Mobile Safari. Neither of the new hacks approach the relative ease of use that we'd seen pre-v1.1.1, but it's still early days yet. Apple, throw us a bone here, will ya?
