Installer problem

[clay]

I upgraded my iphone from 1.0.2 to 1.1.4 and jail-broke/unlocked it using ziphone. Everything works well except installer. Every package I try to install, I get the message "package download failed". Can someone please tell me how to fix this. It happens with both edge and wifi; also the sources seem to update o.k. so it isn't a network link problem. I have looked at other threads for solutions but they all seem to involve downloading software (e.g. bosstool). But I can't download anything (not even "services" to use winscp).
