Development platform for PineTime images?

I would like to start learning to program the PineTime but all the forum postings I have read so far refer to programming the watch using an Android phone, which I don't happen to own. So I have some easy questions, in no particular order... 

Can I develop firmware for the PineTime using my PineBook Pro? 

Can I do any of this before I receive my PinePhone or am I out of business until then?

Is my iPhone 7Plus of any value in this matrix in the mean time?

I have a j-link mini (edu) and a j-link edu. Can either of these be used to program the PineTime using OpenOCD?

Or do I need to buy something else specifically? If so what?

I am really looking forward to getting started :-)

Thanks, Douglas

The answer to all your questions is basically YES.  I programmed my Pinetime using OpenOCD and an ST-Link without using an Android phone.  I had to use a Raspberry Pi to unlock the Pinetime first, but I believe a J-Link can do that.  Once a bootloader is installed using an St-Link or J-Link then the application code can be downloaded over Bluetooth using Linux or Android.  Danielt supplies tools for doing this on Linux.  Danielt and Lupyuen have excellent documentation.

I have a lot of experience with large computers, from mainframes to laptops, but not much experience with smaller devices.  It took me a while and a learning curve but I got there.
