Locked just means it's tied (aka locked) to a particular carrier. So, when you purchase an iPhone (or any phone for that matter) from Cingular, it's locked to Cingular. This means that you cannot use the phone on another carrier. GSM phones use SIM cards, so an unlocked phone allows you to have a "world phone". GSM is prevalent throughout Europe and the world. If you have an unlocked phone, all you need to do is add a SIM card. In the US, that would mean you could use the phone with a different GSM carrier such as T-Mobile. For obvious reasons, Cingular and the rest of the carriers "lock" their phones. They don't want you jumping ship.ok, sorry if this is a dumb question........
But, whats the difference between a lock and unluck phone?
From what I've read and heard (cannot confirm the sources), the iPhone will not be open for software development. I'm assuming Apple wants to minimize support issues. Once you open up to third party software, you open up platform stability issues. The developers will definitely want to start developing on the new platform. There was a thread on Apple's discussion boards regarding this topic.It runs Mac OS X - in Job's keynote, he mentioned it comes with Cocoa, so any mac os program (within reason) should run on the iPhone. Mac os is highly dependent on java, but most programs are written in objective C. I foresee a flood of apps for the iPhone. If you can program the Mac, you can definitely program for the iPhone.
Unfortunately for most, that's incorrect. Cingular has a multi-year exclusive. Not exactly sure about the timeframe, but definitely through 2008. Once I get the definite answer, I'll share it here and in the new iPhone FAQ being put together for the site.If I am now currently using verizon wireless will I be able to use iPhone as my phone? My friend said that this product will be launced in 6 more months for cingular and then for the rest of the provider 6 months since that time. Is that right?
