If you hurry, you can snag yourself an unlocked HTC One M8 on eBay for only $370. It’s a refurbished model and the listing isn’t entirely clear on the exact model meaning this could either be the AT&T model that’s been unlocked for use on any network (comes with AT&T bloatware), or it’s the actual unlocked model normally sold through HTC (updates direct from HTC).
In either case, you’ll probably only want to pick this up if you’re already on AT&T customer, as either model will only offer full compatibility with that network (or global GSM bands). The phone ships free out of California and should arrive well before Christmas. You can find the purchase link down below.
