There is really no evidence to support such a contention. Iran had no reason to help out Carter by releasing the hostages. On the flip side if they weren't going to drag out the situation it was better to resolve it and get some goodwill with the next administration, which they did.
It would have been strange if the US did not supply Iran with weapons given the geopolitical situation. Iran was surrounded by Soviet friendly countries and an Iranian loss to Iraq would have been a disaster for both the US and Israel. Israel, not coincidentally, served as a backchannel for the Iranian US relationship during that time period.
