Transferring data on a SD card to a micro SD card?

I have an iPhone 4 and as far as I know, it has a regular SD card. I want to buy a Docomo Fujitsu F-02D but it uses a micro SD card… I don't want to change phone numbers and I want some of my old data like my friends' phone numbers.

Also, would using the new Japanese phone I'm getting be a problem if AT&T is my provider? The phone would work fine outside of Japan (it's unlocked) but would AT&T have some kind of issues whit me?

What is this part of the iPhone 4 called?

Iphone 4, dies and won't charge past 1%?

The phone is over a year old, it was on 70% charge and then just turned off and wouldn't turn back on, i plug it into a charging point and it powers up but says i have no service and doesn't charge past 1 percent then goes to the black screen with an apple after a few minutes… Is this a problem with the battery that will need to be replaced? Or something a factory reset would solve? Serious answers please thanks

I can't edit any of the music on my Iphone?

When I plug my Iphone (3G) into my computer and load up iTunes, I can't edit any of my music, I can't delete anything, I can't change the names, move things, or even put artwork on! It's really annoying! It's only been like this for a few days now.
I put some new albums on, Red Hot Chilli Pepers, Excision, and they won't show up on 'Artists'. I did find one of the Albums on 'Albums' but I can't edit any of it and I need to do so as the names are wrong, it's in capital letters, no artwork etc. But the other album showed up with like only 3 songs! And when I check on my iTunes it say's that they're all there!
