Although countries such as Australia launched with the iPhone 3G on multiple carriers, the US features both GSM/3G/UMTS and CDMA networks, as well as new 'next-gen' LTE networks, and with Apple's iPhone only being available on GSM/3G/UMTS, plenty of consumers were unable to get the iPhone, whether through poor 3G coverage through AT&T, or because they were on a contract with Verizon and didn't want to change.
Now, the new iPhone release changes that, and all those who longed for an iPhone to be available on Verizon's CDMA network finally get their wish, with Verizon no doubt eagerly awaiting sales and subscriber figures to see whether reports of consumer demand end up matching with today's new reality.
Verizon's iPhone also features a 'Wi-Fi' hotspot, allowing Verizon iPhone 4 customers to share their iPhone's net connection with up to five Wi-Fi devices, be they an iPad, another smartphone, their portable PCs, game devices or anything else that can connect via Wi-Fi.
Questions have emerged as to whether AT&T will offer the same capability, with rumours suggesting that an upcoming iOS 4.3 update will deliver an inbuilt Wi-Fi hotspot capability.
This has led to further questions over whether AT&T will support any such capability, even if Apple technically allows it, given AT&T's sluggishness over switching on MMS and tethering support, even though previous iOS versions made it possible.
Even more questions now surround the impending release of the iPhone 5 and the iPad 2. Will these devices feature 3G and CDMA support in the same device, allowing Apple to ship a single 'world'-compatible iDevice?
More questions emerge on page two, sleuth on over!
