Transferring contacts to iPhone

Transfer the contacts to a computer and then sync to the iPhone. An alternative is that you have the contacts on the HTC in Google, and you sync then to the iPhone after creating your Google account on the iPhone.

Checkout Qikshare. It's a free app that allows you to share contacts along with photos, files, and videos. www.qikshare.io

I use Google Account to do that. Really easy!
