Verizon iPhone 4: What's the Difference?

ByMike Moffit

In the days following the announcement of the Verizon iPhone 4, some have wondered exactly how it differs from its AT&T based sibling. For all intents and purposes, the Verizon handset contains the same hardware and technology used in the AT&T version, but with retooled CDMA compatible guts. Even though the hardware itself did not receive an ‘S’ speed boost, it does contain a few subtle differences.

The most noticeable physical difference, especially in terms of accessories, is slightly shifted button placement on the device’s left side. Though all three buttons retain their same size, they have been moved enough that many cases designed for the original AT&T model will not fit. Reasons for this subtle change are unknown, but it is likely the modified internal components have something to do with it. Those who have had hands-on time with the device have also noted an extra break in the phone’s bezel. While some have claimed this marks a redesigned antenna, exact reasons for the added break are unknown. It is highly probable that this modification was merely to better accommodate the CDMA technology.

A third physical difference between models is that the Verizon version lacks the SIM Card slot found on the right side of the AT&T model. This omission is easily explained by the type of wireless technology implemented on Verizon’s network versus AT&T’s. Unlike AT&T, which relies on GSM technology for its network, Verizon uses CDMA. This technology does not use individual SIM Cards, hence the missing SIM slot on the Verizon model.

The fourth and final difference between the two models comes in the form of included software. As announced during the Verizon presentation, the CDMA compliant iPhone 4 supports a Personal Wi-Fi Hotspot for up to 5 users. While pricing and data details have yet to be announced in relation to this service, it’s still a great option which would allow up to 5 Macs, Wi-Fi iPads, etc. to share the phone’s 3G connection. On the display models of the phone circulating post conference, attendees discovered the Personal Hotspot option is located immediately within the phone’s Settings app, on what appears to be either a new or custom version of iOS 4.

As announced Tuesday, the Verizon iPhone 4 will become available for pre-order to existing Verizon customers on Thursday February 3. The phone will become publicly available at Apple and Verizon Wireless stores a week later on the 10th. You can learn more about the device here.

  • What Is the Archive Utility?

    A long-time Small Dog customer asked me about an item that fleetingly appeared in his dock. It was a generic-looking green icon with a zipper on it called Archive Utility, and when he used Spotlight to search for it, it was nowhere to be found.

    Many of the items you download and receive in your email are compressed files. File compression is nothing new, and is exactly what you think it is: when you compress a file, you make it smaller. This reduces bandwidth loads and expenses on the server side, and can help you save disk space on your computer. However, compressed files cannot be directly accessed; they must first be decompressed.

    Back in the days of twenty megabyte hard drives (my LC II had a 20 megabyte drive in the early nineties), file compression seemed more relevant for conservation of hard disk space. These days, it’s more often used to shrink email attachments and other downloads. Mac OS X always included a built-in compressor and decompressor. By right-clicking on any file or folder in the Finder and selecting “Compress” from the contextual (pop-down) menu, your Mac will create an archive in zip format.

    When you open a compressed file, Mac OS X launches an application called Archive Utility. Its sole purpose is to compress and decompress files. It’s located in /System/Library/CoreServices, and Spotlight doesn’t search there. If you poke around the /System/Library and /Library areas of your hard drive, there’s plenty to learn if you Google intelligently and use extreme caution when moving or deleting anything. Actually–don’t move or delete anything. Just explore and learn!
