iPhone 4 / iOS4 New Features
This post is quite a bit late already as the iPhone 4 has been released a few months ago. However, I know the following are really useful bits of information, so read on! (Reference: iPhone Support documentation)
Antenna (low signal / dropped calls)
The iPhone 4 has a new Antenna system. If you are having reception issues, Apple recommends getting a bumper case that will help safeguard the antenna from touch. To avoid poor reception issues if you don’t want to use a bumper case, make sure you hold the device by not touching the area where the black strips are at the bottom of the unit. It is also recommended to update it to iOS 4.01 or above which corrects an abnormality in the signal strength meter.
Cellular Data
iOS4 includes a new feature called Cellular Data – it allows you to turn off DATA CONNECTIVITY while still being able make and receive voice calls and using SMS. This is good if you are one of those users who wish to turn off data to conserve battery life or to safeguard against accidental roaming charges. When this option is OFF, you will not be able to use MMS, Tethering, use Visual Voicemail (the phone will still allow you to call into your voicemail box from the voicemail screen), and any application that requires data or location services will not function.
FaceTime
FaceTime is Apple’s new video calling feature, which is only available if you and the person you’re calling has an iPhone 4 as it requires the front facing camera. At the moment it only works through WiFi – 3G service is expected to be coming later this year (with Rogers Wireless users). If you are experiencing issues placing a call after porting your number, follow the steps HERE.
Should you have issues placing FaceTime calls and are behind a firewall, make sure you enable port forwarding for the following ports 53, 80, 443, 4080, 5223, and 16393-16472 (UDP). Refer to your router manufacturer for assistance or to your local IT Group.

You can only copy five images at a time into an email. You can also now share up to nine images via MMS and five via email.
