Since I a have Jailbroke my iphone 3GS using JailbreakMe, I keep having wifi & 3G issues.
In settings when I have wifi on it says connected to my network, however when i use any app that requires internet, they do not work, and the wifi logo doesn't show-up. This problem sometimes occurs if I am at home using wifi, go out for a bit, leaving wifi on. Come home says its connected but doen't do anything.
I also have a issue when I am in a 3G area, my phone shows I am connected over 3G but if I use safari etc, it says no internet connection found!!
The only solution I have found is to turn the phone off, then turn it back on!!! I think I have seen somewhere that this could be a baseband issue, anyone know??
I have SHSH stored on cydia for IOS 4.0 and 4.0.1, do i need to do a restore?
I have now restored my iphone to 4.0.1, all the above problems seem to be resolved!! Don't know if my issue had something to do with using "jailbreakme.com" the day it was released??
