Cydia Apps not downloading with 2.1

[bored911]

so i had 2.1, unjailbroken, then used quikpwn to jb. easy enough. now however i continuously get the error message

NetDB: apt.modmyifone.com nodename nor servrname provided, or not known

does anyone know why this is happening for a large number of apps? it seems like a network error but i see no way of fixing it. NOTE: some apps do seems to work ok, such as winterboard.
