Problem : No GPS signal, they are almost dead. You won’t find even a single tower connectivity in Navigation applications like Sygic.
Here is a working solution to fix it to great extent.
Solution: You need to install Pushfix 3.1.3 using “Cydia”.
Go to Cydia -> Sources -> Edit –> Add http://fishbone.ge
Search Pushfix and install it. (P.S. After installing PushFix all wireless network passwords, email passwords are deleted, you just have to update them again.)
Please Note the wireless(Wi-Fi) needs to be always active, it does not matter whether it is Connected or not. It will not point your accurate position there may be an error up to 10 meters. Also it will not show full signal bars in Navigation Applications. The pointer will move as you go but may not display your speed.
Well this is like heaven instead of having a dead GPS. 🙂
