Correct and you most likely destroyed the battery cell. Li-po cells should never be allowed to discharge below 3.0 volts.
Matbe you overlooked the fact that OP is using a Nokia-pack, and therefore (if it's not one of those clones that's extremely dangerous) it's a protected pack. These kind of batteries are almost idiot- and fool-proof. Over-discharge them, and they'll go open circuit until you try to charge them again. Short-circuit them, and they'll go open circuit. Over-charge them and they will go boom though
