There are several things included in the iPhone 3.0 MMS release that users may not be aware of until they start flexing the application. The key here is that you can send much more than photos. Information from your Contacts can be sent via MMS by touching the Share Contact button when viewing entry details.

Similarly, touching the share button in Voice Memos will give the option to send via MMS or email. The iPhone 3GS will send video using MMS, although it will severely degrade the size and quality. This helps to insure the video will play on smaller and older phones.

Some iPhone applications have preferences to set an accelerometer lock, which keeps the orientation of the app in one direction no matter which way the iPhone turns. Unfortunately, most commonly used apps do not have this feature.

Rotation can be switched off when viewing photos on the iPhone Camera Roll or Photo Library. When viewing a photo, hold down with one finger on the photo as if you're trying to copy the image.

How about making iPhone calls on your own personal cell tower? AT&T has test launched its femtocell solution for individual users, dubbed the MicroCell. This device is compatible with the iPhone 3G and 3GS.

MicroCell data speeds will be slower than the 7.2 Mbps the iPhone 3GS is capable of delivering, however they will achieve 3.2 Mbps, matching standard 3G speeds. The device allows users to make calls and send text messages using a 5,000 square foot local 3G network.
