I am unable to purchase any package in Cydia that has not been previously purchased using my iPhone 5 on 7.1b2. Cydia states "unable to purchase", claiming my ios device is not supported. I've already removed the expiry using the thread here on macrumors, so I plan on staying on this firmware if 7.1b3 includes patches by Apple to close the JB. I don't want to downgrade to 7.0.4 as 7.1b2 has been very stable. I did try to spoof my version by changing the build to ios 7.0.4's and version to 7.0.4 instead of 7.1 on that .plist file. Settings read 7.0.4, but Cydia still shows 7.1 even after a reboot. I can download free packages, just not purchase anything. I want to buy some themes and tweaks but unfortunately this won't let me and I don't want to resort to piracy-filled repos. Has anyone been able to spoof Cydia into thinking your 7.1b2 device is running 7.0.4?
