my new iphone

Hi!
I just got my iphone and tried my earphones today and sadly only one of them is working. I cant find on ebay seperate earphone for this cect 168. Where do you think i can get some?
Has anybody found a coverter that works so i can use my normal earphone? Is a bloototh earphone better, does anybody use one?
Oh and also, i bought this phone unlocked for hungarian networks as well but it does not recognise my hungarian T-mobile sim card, what can the problem be?
It is an old simm card, does that make any difference? I have no idea what band it is on, how do you get to know that?
I would be gratful for any help!
Thanks,

 

i think there is an adapter to use regular headphones on ebay

 

HI!!

Since that message my adapter is on its way. I got it from ebay, they say it is good.
And i worked out my network problems as well
I just dont know what sort of micro sd card i can buy in this phone, i would like to put more music and clips on it. Do u know where and what i should buy??
Thanks

 

Kingston microSD card works great! I have used it for a long time.
