Big news for iPhone 3G and iPod touch 2G users! After learning about iPhone OS 4 jailbreak news earlier today, some iPhone devs/hackers have now apparently managed to enable multitasking on the older iPhone 3G and iPod touch 2G, both of which were limited by Apple due to lower amount of RAM on these devices. This is what a recent tweet from an iPhone dev said.

According to a recent job posting, the Cupertino based company is looking for a engineer to lead a group of software engineers in order to bring iPhone OS to new devices and platforms. The job description is as follows.

As was predicted, CEO of McGraw-Hill has confirmed in an interview to CNBC today that Apple is going to announce their Tablet on 27th and it will run on iPhone OS. Terry McGraw, who is the CEO of the famous publishing company further went on to confirm that they “have worked with Apple for quite a while” and that it will be based on the “iPhone operating system”.

Sources close to BGR has dropped some exclusive information regarding the upcoming iSlate/Tablet device from Apple. The said device, which is likely to be announced on January 27th will feature a very fast ARM processor, and will run on top of iPhone kernel. Details, as stated on Boy Genius Report site are as follows.

Remember all those rumors regarding Apple’s tablet launch in January? Well according to fresh reports from All Things D and Mac4Ever, Apple is set to unveil a “major” product (most probably the iSlate tablet) come this January 27th, and not January 26th which was reported previously. This mega media event will be held at Yerba Buena Center for the Arts in San Francisco.

Last week we informed you about the first evidence, which hinted towards the possible existence of iPhone OS 3.1.3, and iPhone 4.0 firmware. Today, MacRumors has been tipped by a developer who has spotted a single instance of iPhone OS 4.0 being used in his application’s Pinch Media analytics data. This discovery corresponds to the discovery of “iPhone 3,1” (the next-gen iPhone 4G model), which was spotted by the developer of iBart app last month.
