Member: 904753 Status: Offline Sonork: 100.1583681 Thanks Meter: 2,677 | Good Progress on iPhone 4 Unlock The ‘baseband’ is the generic nickname given to the internal components of the iPhone that handle the phone calls and Internet access. This ‘baseband’ is a tiny and unique independent computer system that runs inside your iPhone, it is separate to the main system that handles the applications (such as email and google maps) and it talks to the main part of the phone over an internal communications network. Think of it like a cable modem or other peripheral that is attached to your home PC that needs occasional updates. When a software update is released and presented to you within iTunes the baseband is sometimes updated (to fix bugs or add new features). When iPhone 4 was launched, folks at *****I had reported that: The DevTeam and others have been checking through the iPhone 4, and have noticed the baseband runs a completely different OS than on previous models. The iPhone 3G and 3G[S] both ran Nucleus OS on the PMB8878 baseband CPU (aka XGold 608), where the iPhone 2G ran the PMB8876 (aka S-Gold 2). iPhone 4 uses the PMB9800, or X-Gold 618 – running a separate OS – ThreadX, an RTOS by ExpressLogic. We had reported that MuscleNerd and planetbeing of the iPhone Dev team were having fun playing around with iPhone 4 baseband to figure out how to unlock it. It looks like they’ve made good progress as MuscleNerd has just tweeted: Good progress on iPhone4 unlock with @planetbeing: Twitpic - Share photos on Twitter <-injected cmd! (Akin to 3G Baseband Tool on Vimeo on 3G) Next step is to keep the task backgrounded like we did for 3G/3GS Persistent Nucleus Tasks on Vimeo. Backgrounded task is the unlock. As you can see in the screenshot below, they’ve managed to run arbitrary code on the iPhone’s baseband and are a step closer to unlocking iPhone 4 baseband. MuscleNerd: "Next step is to keep the task backgrounded like we did for 3G/3GS Persistent Nucleus Tasks on Vimeo. Backgrounded task is the unlock." MuscleNerd: "Steady iPhone4 unlock progress with @planetbeing...custom "pp" command to dump thread priorities" MuscleNerd hasn’t provided any details about when the tools to unlock iPhone 4 will be available. But we doubt Dev Team will release them before Apple releases the iPhone software update (iOS 4.0.1) to fix the incorrect reporting of signal strength to address the iPhone 4 reception issues. As always, we’ll let you know as soon as we’ve any further updates. So stay tuned here Br. Waqar |

Member: 1411624 Status: Offline Thanks Meter: 0 | Can't wait, I have an iphone 4 which I cannot use although I have replaced the broken screens for £130 and bought a sim card-it's still locked for calls, though I can listen to music on it and take photos, so not all bad. |
