Q.  fail2ban before 0.8.8 temporarily unban an address

A.  First list all iptables rules.  Chains starting with "fail2ban-" are
for fail2ban.

iptables -L -n
Or try without the -n to see names (which can add some info)
iptables -L
Note the chain name (case sensitive, based on your jail names) and IP-address. Then do:
iptables -D <chain> -s <ip-address> -j DROP
For example
iptables -D fail2ban-ProFTPD -s 1.2.3.4 -j DROP
fail2ban after 0.8.8 has an option with the fail2ban-client command
fail2ban-client set <jail> unbanip <ip-address>
