Question

Is there a way to install iPhone App via a browser (in this case iOS Safari)?

Answer 1

Yes, safari will detect the *.ipa and will try to install it, but the ipa needs to be correctly sign and only allowed devices would be able to install it.

http://www.diawi.com is a service that will help you with this process.

All of this is for Ad-hoc distribution and not for production apps.
