iOS 4.3 has a new Personal Hotspot feature, which turns your iPhone 4 into a 5-device mobile hotspot. It lets you use your iPhone’s 3G connection with WiFi, Bluetooth or USB. But to use this feature, the carriers are charging an extra monthly fee on top of your already expensive phone bill. Well, there’s already a jailbreak tweak called TetherMe that will enable this feature for only $0.99. Just search for TetherMe in Cydia to purchase and install it.
