How to Add Phone Number Extensions to Your iPhone Contacts

Sometimes waiting for automated phone menus and dialing extensions can be a real drag. Luckily, the Apple iPhone has an easy way to automatically dial extensions when needed.

All you need is the contact you're trying to reach and the relevant phone number and extension you'd like to add to the contact information.

How To Email Full Resolution Photos From Your iPhone

Did you know that when you email a photo from the camera roll on your iPhone, the resolution of the picture is automatically degraded to 800x600? This makes sense if you don't need to send anything at a higher quality resolution.

But what if you need to send the full resolution photo? The original iPhone and iPhone 3G both take photos at 1600x1200 resolution. The iPhone 3GS with its auto-focus camera takes photos at 2048x1536 resolution.

Tip: Show iPhone Battery Percentage Remaining

The little battery icon in the taskbar at the upper right of the iPhone screen is okay at giving a rough indication of battery life remaining. Unfortunately when it comes to details the icon is not so useful.

Luckily there are ways to display the exact percentage of power remaining on your iPhone battery. There are two different methods you can use to achieve this goal depending on your iPhone hardware.

How to Downgrade From iPhone Firmware 2.2

Many users have been reporting problems with the iPhone firmware 2.2 upgrade from Apple. It may be that the best way to solve these problems is to take a step back and downgrade to firmware 2.1. Others inadvertently upgraded their phones when syncing to iTunes on their computer and for whatever reason would like to revert.

The process is relatively simple and should bring back the 2.1 version OS to your iPhone. Performing these steps on an iPhone 3G may work, however this article does not cover reversing the 3G baseband update included in firmware 2.2. Remember, taking these steps is at your own risk, and any hacking of the iPhone could render your remaining warranty invalid.
