It is not news that iFixit has got its hands on a Verizon iPhone, but they are not using the iPhone for making phone calls – they reckon that there are plenty of others already doing that – so they tore it apart instead!

Their dissection of this new device resulted in some unexpected and pleasant surprises. They found that the Verizon iPhone carries a slightly lighter battery than its counterpart – although of the same capacity – and the mechanical vibrator has been redesigned and moved from the top right to the bottom left corner of the phone.

The most notable thing about the new version of the iPhone is that it has a Qualcomm MDM6600 chip supporting HSPA+ data rates up to 14.4 Mbps and both GSM and CMDA – this is not surprising as it is the same chip as used in the Droid Pro.

However, the lack of a SIM slot has some disadvantages – one of which is to complicate the process of unlocking the phone for use on other carriers. Previous iPhones were (relatively) easy to unlock for use with another carrier’s SIM card. A report quoted by ‘AppleInsider’ states: “unlocking Verizon’s iPhone 4 will be virtually impossible to do because it would require using an ESN/MEID from a donor phone with service. This technique is a US federal crime.”

Another difference in the Verizon iPhone is that it only supports the 800 and 1900 MHz CMDA EVDO bands used by Verizon, whereas its counterpart supports four GSM bands (850, 900, 1800 and 1900 MHz) and four UMTS bands (850, 900, 1900, 2100 MHz).

Apple has noted that the Verizon iPhone lacks user serviceable parts, and now the iDevice uses ‘pentalobe’ screws to deter users from opening up their iPhone.

Some more news regarding the new version of the iPhone is that the shape of its logic board has been redesigned to accommodate the new vibration motor and silent alerts.
