Since I got the my iPhone 4 with AT&T I lost 2 bars comparing to the iPhone 3Gs I had before, so I got AT&T 3G MicroCell.

Now – my Verizon users co-workers laugh at me.

The new iPhone 4 is Amazing.

Front facing camera, FaceTime, LED flash, speed, the screen, folders, multitasking, HD video, speaker quality, design, multiply exchange servers.

All and more are GREAT FEATURES.

BUT…..

To make it short, anyone that ported his/her number to AT&T from a different carrier for the new iPhone 4 will have issues using Facetime, read the full story to understand the problem and the solution.

Here we go:

On the 24th I upgraded my iPhone at an Apple store.
I also got a new iPhone with a new line and ported the phone number from T-Mobile. (2nd phone)

The Apple store employee that helped was very nice and the new iPhone worked great, including FaceTime.

Once my T-Mobile number was ported FaceTime stopped working.

The iPhone could not receive FaceTime calls but could initiate FaceTime calls.
When I tried the caller ID that appeared on my UPGRADED iPhone were the Other iPhone New Temporary number I got until the port from T-Mobile completed.

If you are like me, trying to PreOrder or Reserve your new iPhone 4 but CAN’T!!

Do the following:

1. Go to the App store
2. Download the new Apple Store App
3. Reserve your iPhone to pickup at a store near you

This is the only way that I found working at the moment, Good Luck!

First we’ve seen ATT Upgrade eligibility jumping from November 21st to June 20th.

Now we can see that iPhone Upgrade eligibility already Available.

Does it mean that Apple will allow iPhone 4 Pre-Ordering starting tomorrow?

All hints leads for iPhone 4 in stores at June 18. It looks like ATT & Apple learned from last year mistake and making sure that Apple Fanboys will be able to get the new iPhone without standing in line.

Did your upgrade eligibility changed today? Please let us know.
