How to transfer from a nokia to an iphone 4?

I normally use a Nokia 6300. I have just bought a second hand Iphone 4, went to transfer the sim card but it's too big for the sim card space in the Iphone. I'd like to know how i can keep all of my sim card details/texts/photos/messages and tel number and swap to using the Iphone? I'm not very technically minded. Have had the same Nokia for years! Please explain in simple terms.

OK so what you can do is go to your service provider such as sprint for example and ask them to pull the data off the sim card for you and they should be able to transfer the data to your new phone for you hope this helped have a nice day and good luck

Use Nokia PC Suite
