It was reported recently that Three has blocked access to Cydia over its 3G service. All thought that it was an anti-jailbreak campaign. But later came out to be that Cydia was blocked as a part of an adult content filter. This adult content filter is active on most of the accounts.
How to unblock Cydia on Three’s 3G Network
1. Just call 333 from your phone on Three’s network and ask them to turn off your adult content filter. That’s it. Isn’t it simple enough 🙂 ? Thanks to @Prenvo for pointing this out.
With just a phone call, you can download all your favorite themes and tweaks again.
