It may be a lot, but I really need help

Recently, I had a brain fart and left my Touch on top of my car and drove off. I had one of those gel skins on my phone so it stuck to my car for about 5 minutes and then I heard thump, thump..thump thump..

Clearly my Touch was no more, and I was sent a Diamond as a replacement..

Now my issue:
I have the everything data plan $120 or so a month. I had this same plan on my Touch and was able to tether for internet..Now I have the Diamond and no tethering..The option to yes..but then some Sprint pcs vision bull kills my connection

So I call Sprint..and I get well you don't have a internet sharing option on your plan..and actually with your plan you can't add this feature..
>>at this point I'm somewhat heated
Next I get..It will be take me to get a new plan and pay $45/month to share the internet connection I'M ALREADY GETTING..

I don't want to do this..my dead Touch had its ROM flashed. I know I can flash the Diamond's ROM, but will it help my sharing issue
