Wanna enjoy iPhone on a BIG screen!!. It maybe possible in the coming year or so. A 58″ Full HD capacitive screen table is in the making to which an iPhone (3GS and iPhone 4 as of now) can be connected and the exact simulation of it comes alive instantly.
Yes, you read it right, all the existing and future iPhones can be be jail broken unless Apple comes out with a completely new phone ie. iPhone 5 (if rumors are to be believed). The exploit found by Chronix team and Pod2g confirmed on twitter that they have a found a Bootrom exploit not dependent on what version of software running.
