SIM card in iPhone

[MrMister]

How do you put a sim card in an iPhone ?

[ChuckFickens]

Stick a little pin (straightened paper clip will do) into the little hole in the sim caddy and push.

oh actually I seen it on youtube.

Thanks anyway.

Any tips on how to save battery life ?

[ChuckFickens]

Turn the phone off?

[ChuckFickens]

Sorry :)

Serious answer... turn off any thing you are not using like wi-fi, GPS, bluetooth, and even 3G if you don't need data and also set the screen as dim as you can.

Turn off bluetooth and wi fi in settings when you don't need it.

On an iPhone on PAYG, how much would it cost to download or even use an app ?

[Milvus]

Set auto-lock (Settings, General) to 1 minute. This will turn your screen off when you aren't using it.

It will tell you how much each app costs to download then it's free to use as much as you want unless you've jailbroken your phone and you can downloads loads of apps for free
