IPhone – How to access to internet in iPhone 4 with USB or other way through the mac book pro

You can host your own calendar (CalDAV) and contact (CardDAV) server using Mac OS Server ‘Leopard’ or Server ‘Snow Leopard.’ These will sync over the Internet to iCal and Address Book on your Macs, and to your iOS devices.

If you don’t want to get an expensive Mac Mini Server you could go with using an old retired notebook or even a virtual machine with a Linux installation. The open source project DAViCal will provide you with both CalDAV and CardDAV services.

I am personally using an installation of DAViCal too keep my Macs and iOS devices in sync using a older machine I have at home as the server. I would recommend this solution as you remain in control of your own data. Getting it up and running requires some work, but you would be able to congratulate yourself with the accomplishment. There are step-by-step tutorials for setting up both Linux and the DAViCAL software available.

This works well for iOS 10 and macOS 10.12:

• Can I share my iMac's internet to iPhone or iPad over USB??

You're not the first to ask this question. Searching with Google shows that it's been discussed here and here.

Unfortunately, iOS 9 and earlier do not support what you're describing.

You mention that you don't have a wireless card but perhaps you can share your internet connection wirelessly, through an Ad-Hoc network. I think that's the best way to go, honestly.

This doesn't work for internet:

[PC] --->--(USB)--->--> [iOS Device]

But this probably would, since the iOS device doesn't care, for the most part, where the WiFi is coming from:

[PC] --->--(WiFi)--->--> [iOS Device]

So, you might consider grabbing a wireless card for your PC. Alternatively, a jailbroken iPhone might be able to get more mileage with a USB cable than a vanilla one would.
