Developers have been busy digging into the internal of iOS 4.3 beta ever since it was released to developers of iOS Developer Program earlier in the week and not surprisingly they have found something interesting.
Developers have already found references to “iPhone4,1″, “iPhone4,2″, “iPad2,1″, “iPad2,2″ and “iPad2,3″ in the iOS 4.3 beta file system.
Apple uses these models numbers to distinguish between different hardware models.
For example: The original iPhone carries the model number of “iPhone 1,1″ while the iPhone 3G is labeled “iPhone1,2″ and iPhone 3GS is labeled “iPhone2,1″ and iPhone 4 is labeled “iPhone3,1″. These numbers do not change for simple storage increases and instead represent functionally different devices.
In case of the iPad, iProd1,1 was the original reference. But the reference of the production model is iPad1,1.
Based on this, it looks like Apple is working on two new iPhone models (“iPhone4,1″, “iPhone4,2″) and also three new iPad models (“iPad2,1″, “iPad2,2″ and “iPad2,3″). In case of the iPhone, the second digit probably represents a GSM iPhone and a CDMA iPhone with the launch of Verizon iPhone earlier in the week. In the case of the iPad, the second digit represents a Wi-Fi only mode, iPad Wi-Fi+3G model that works on GSM network and iPad Wi-Fi+3G model that works on CDMA network (we’ve heard rumors that Apple may release a CDMA iPad on Verizon’s network).
We’re eagerly waiting for the new iPhones and iPads, which is expected to be launched in June/July and March/April time frame respectively? How about you?
