FB 4.5.1 problem installing iOS application

[Guest]

I have gone through one of the Adobe tutorials to create the Twitter Trends mobile application using FB 4.5.1.  I then went through the well-documented process to install this app on my iPhone (signing up as an Apple developer, setting up the phone, etc).  I am able to produce the .ipa file needed to install the app on my iPhone.  However, when trying to install via iTunes, I get the following error:

The app "<appname>" was not installed on the iPhone "<iPhone>" because it is not compatible with this iPhone.

Has anyone seen this error before?  The iOS is up to date (4.2.1) as is my version of Flashbuilder.

Is your iPhone supported by AIR 2.7?

So sad ... guess I can't read.  Need to trade this thing up anyway.

Thanks -

Sorry!

If you want an explaination, it's the ARM chip in your device that is too old and since Apple doesnt support it anymore (cant install 4.3 on iPhone 3g), Adobe had to do the same... It's how they got 4x faster apps on iOS
