-The New York Times columnist David Pogue asked Apple about iPhone 5 within 5 to 6 weeks. Here’s what Apple said:
Apple won’t say if there will be an iPhone 5 for Verizon this summer. (“Let’s put it this way: We’re not stupid,” is all an Apple rep would say.) But if it does, and you buy an iPhone 4 now, you’ll be stuck with an outdated phone in only five months.
Obviously Apple won’t pre-announce the iPhone 5 because no one will buy the iPhone 4 today. As Apple says, “We’re not stupid.”
-Greenpois0n has just released in Mac version. It s an untethered jailbreak for iOS 4.2.1 without the need for SHSH blobs. The exploit they are using has already been patched in iOS 4.3.
