For those still waiting for an untethered jailbreak for iOS 5. I think you still got one hell of a time to go. pod2g from the Chronic Dev Team had just tweeted today that they had found an exploit recently which might be able to use for an untethered jailbreak. But don't hold your breath though. As no date had been confirm on the ETA of it. As for me, I am running my iPhone 4 on iOS 5 for weeks now with Redsn0w. No worries of reboot till date and I am covered since both my desktop at home and notebook in the office can be use to reboot it. Settled~!
In another note, for those who heard that someone successfully ported SIRI to iPhone 4, well it's fake. We did heard this news before after the launch of iPhone 4S that someone DID managed to do it but since it's against the law to port it over to another iDevices other than iPhone 4S, hence the idea had been put to rest. But recently, there are rumors that Apple are doing testing or experiments with SIRI running on other iDevices namely iPhone 4 and 3GS. At least they are agreeing that SIRI are able to run on other iDevices other than the new dual A5 processor. Hopefully they are finally opening up their mind on this. We'll keep our finger cross on this for now.
