Mate, if you look at your iPhone's headphone jack, you will see a quite small hole next to it. All you need to do is insert a pin into that hole and the tray will pop open on top on the phone.
It's in the middle of the Power button and the earphone slot. You will see a small hole on top. stick a small paper clip, bobby pin, pin, etc. into the hole and push lightly down. A slide containing the SIM card will eject and you can pull it out and eject the card.
on the top of the phone next to the plug for the earphones, there is a small pin hole u need to insert the pin that came with the phone and it will pop out the sim case
The SIM card is usually in the side or back of the phone, if it is in the back of the phone you have to take off the back cover and sometimes the battery also.
No
any AT&T phone that can take that sort of sim card.
Yes, Yes you can.
You put a sim card in it.
Yes as long as the phone is att and has a sim card slot
If your 3GS is locked, you can't insert a SIM card.
Yes, but only if you unlock you iphone
As long as it is AT&T, yes.
the iphone has a sim card which slots in the top of the iphone. to get the sim card tray out you have to use a pin or the special tool it came with to open it.
Yes it can be swapped. I actually swapped my razr's sim card to my iphone. Nothing happened. It works perfectly.
Yes, you will have access to all the features. It doesn't matter what SIM card is in your phone because the phone needs a SIM card, given to you by a carrier, that is supported by the phone to operate. Just put the SIM card in the HTC Wildfire and put it in the iPhone.
