My phone has no Wi-Fi functionality so I am unable to access Cydia the normal way.
I don't understand.
for certain tweaks, they rely on other tweaks known as dependencies. for example, to install SBSettings, you need to have libhide, mobile substrate, shell-cmds, libactivator, and wee loader installed already
just curious but why does your phone have no wi-fi functionality?
opening cydia, i search for macx4 and find "macX4 MAC Changer (iOS 4)", is that what you are trying to install?
In order to install iFile, you must have the dependencies file-cmds, zip, unzip, p7zip, gzip, bzip2, unrar, and diskdev-cmds installed already (going about the way you are installing the packages which is one at a time). If you install any tweak/app using cydia, it installs it all (the tweak itself and the dependencies) at once for you
