Today, it seems that MacWorld, Engadget and other sites has gotten their hands on the iPhone 4 on Verizon’s network.
As a lot of you already know, there no new features on the Verizon iPhone, only the the obvious: that it runs on Verizon’s CDMA Network.
That’s what this new iPhone is: a redesign of the iPhone 4 that works with CDMA cellular networks. If you want to switch from AT&T to Verizon, you’ll need a new phone. If you get this phone, you can’t take it to AT&T later, nor can you roam internationally in as many countries, since CDMA is much less popular worldwide than GSM.
The Verizon or CMDA version of the iPhone 4 comes with IOS 4.2.6. The only new feature that comes with this update is the Personal Hotspot, which allows you to tether or share your iPhone 4 data with other devices.
The CDMA version of the iPhone 4 ships with a new version of the iOS, 4.2.6. Presumably the software is full of modifications that allow the iOS to drive the new CDMA radio hardware, but the only noticeable change in features available to regular users is the introduction of the new Personal Hotspot capability.
One of the feature that the iPhone 4 losses on Verizon’s Network or being a CDMA model is that you won’t be able to talk while you use the internet; use voice and data simultaneously. The Verizon iPhone will only do one at a time.
Adopting the CDMA cellular standard does force this iPhone 4 to take one step back—back to the days of the original iPhone, in fact. Unlike AT&T’s 3G network, which can transmit data and voice simultaneously, the Verizon 3G network can only do one or the other.
Engadget has tested the data speed and compared it with AT&T and here are the results they have gotten:
As all that being said, you should pick your iPhone 4 based on which carrier has better coverage around your area. But in my opinion, if both carrier got good coverage around your area, you should stick with AT&T. With AT&T, you can switch your SIM card to any other phone fast without have to call to get activated. You will also still have the ability to use the internet and voice at the same time.
