Apple are having problems getting wireless carriers to agree to their terms on selling iPhones, with Bloomberg reporting that Apple "is missing out on a chance to court as many as 2.8 billion new smartphone customers, many of them in Asia, as wireless-service providers balk at conditions imposed by the iPhone maker and drag their heels in signing on as partners".
Bloomberg has estimated that Apple have agreements with around 240 carriers across the world, but main competitor Samsung has agreements with over 800 carriers. Big carriers such as China Mobile and Japan's NTT DoCoMo have objected the "high costs of subsidies needed to make the device affordable or other terms they find unacceptable".
This will mean that Apple will have to make the deal more appealing, or risk losing out on countless customers in emerging markets. This is where a cheaper iPhone would help, or if Apple decide to change their ways. Up until now they've not had to worry about this, but with their stock prices absolutely tanking, and sales sputtering to a stop, this is the time when Apple needs to change.
