Is there any way to obtain and install the previous version
of iAnywhere on an older iPhone 3G running iOS 3.1.3?
iTunes shows the latest version doesn't target the older
iOS.

What's New in Version 5.7.2011.0314
- Client requires iOS 4.x
This client will only install on devices running iOS 4.x.

Can I obtain the older IPA/APP file and push it to the
handset using a manual iTunes sync or even a configuration
profile or something?

Thanks in advance for any assistance, cheers!
