I found this on another site, worked for me with iphone 4 ios 6.1
Found a way to make this work now Instal0us doesnt work, its quite simple really just needs 3 downloads works for all IOS firmwares including 6.1
Download Sky Go IPA From Uploaded.net
skygo.ipa (6,70 MB) - uploaded.net
Download Xcon Beta 38, make sure you uninstall newer versions from Cydia
http://goo.gl/BHB4p download link for Xcon beta 38. (Do not update in cydia once installed even tho it asks you too)
Download Ifunbox & install
http://www.i-funbox.com/windows or mac download to PCM or mac
Once you have all the above connect your idevice via USB
Open Ifunbox, to install the Xcon .deb file go to "ifunbox classic" and "Raw File System" then navigate to var/root/media/cydia/autoinstall goto your desktop or wherever you downloaded the xcon .deb file grab it and drop the .deb file into the folder in Ifunbox then turn off and turn on your iphone/ipad turn it back on, then turn it off and back on again, you must do this step "twice" this will install xcon 38 beta, you can check in Cydia to make sure it is installed, it will show an update for xcon in Cydia, do not install it
then in Ifunbox Click "Managing App Data" Then install app Locate the Sky Go .ipa you downloaded and install it.
Run Sky Go and off you go
