I realize this is unsupported, but I'm wondering how feasible and difficult it would be to reprogram a Virgin Kona to be used on Ting. I have a donor phone if necessary and I'm just wondering what the basic steps/tools are needed to begin research. I know it's a hassle and I would just buy a sprint version on eBay, but haven't been able to find one. Never thought I'd say this, but I wish Sprint would release some more decent feature phones.
EDIT: Now Ting has the Kona. At $88 bucks, a bit steep for what it is. https://ting.com/devices/buy/kyocera-kona
