Mobile Evolution

My iphone (bought in the Philippines, using in Canada) froze so i pressed the home and unlock button at the same time. I’ve done that couple of times but last night it said to connect my iphone with itunes so i did. Then, it said to restore it so i did. Then now it says the sim card inserted in this iphone does not appear to be supported. Help me please, tell me what to do.

I have a 1G iPhone. Is there a way to sync photos from my gmail contacts to my iPhone and vice versa?

I am considering buying an iphone but really want to be able to access internet in most places. Especially to use the map feature… I get lost everywhere.
I considered getting the ipod touch but I’m afraid I won’t be able to find wireless in most places.
What is the iphone’s EDGE network and can you connect to it anywhere?

I had my iPhone on our family computer, but for Christmas we got a brand new family computer and I got a laptop. My iTunes account is still on the old computer and the credit card it was charging to is now shutdown and I really want to be able to buy more songs off the computer. Please help!

I know that the iphone works for at&t but does it work for any other company?
