I recently got my iphone4s jail broken, as I have moved abroad. Since putting in a new sim (vodaphone Egypt) the reception bars and 3g appears, but i am unable to connect to internet and has the waiting sign constantly running.
The only way i seem to get onto internet and make call is if i make a call which it initialy fails.. then the reception bar goes to 'searching' then back on to full bars and 3g, but this only last for about 10mins or when i lock my phone, then i have to repeat the whole process again.
also randomly ( not often) it goes to invalid sim.
If i have a wifi connection the internet works fine everytime.
Any ideas what it could be and how to fix it. could it be to do with the jail break?
Thanks in advance
