Fix Certificate Error for Nokia E71,E71xE72,E75,E63,E61i And 5800 Themes

By default, some Nokia devices have the security settings set too high and a couple of changes need to be made in order to install Nokia themes. Nokia E61i, E63 and E71 and E71x in particular suffer this problem. However the fix is easy.

Go to “App. Mgr.”,
press “Options”,
press “Settings”,
make sure “Software installation” is set to “All”,
and “Online certif. check” is set to “Off”.
After Doing This Every Theme will work fine without any error on your Nokia E71x,E71,E63,E61i.

"Call Ended" and then "Call Failed" in iPhone....

If you see "Call Ended" and then "Call Failed" immediately after trying to dial out from your iPhone.....

There probably is no problem with the phone. I had the same thing happen to me - iPhone 1.1.4
Just remember these 2 steps:
1) Settings > General > Date and Time > (Here, switch off "Set Automatically" and manually select your hometown). Then manually set the date and time.

Apparently the SIM and carrier wont work if date and time aren't set well, make sure date and time are the current ones

2) Settings > Phone > Show My Caller ID > Switch ON

Usually people who virginize or upgrade or even first time unlockers - forget to change the default Location setting - which is Cupertino. If you dont change it, you will not be able to make outgoing calls. But the wierd part is, you will still be able to receive incoming calls.

Hope that helps!
