I recently bought this phone second hand from a shop called CEX. firstly, i inserted a three sim card and everything works fine, wi fi the lot. the 3G icon is on the screen but i can't access the internet why is that? it works with the wifi but not with 3G. The other problem is the SD car slot, a friend of mine gave me his scan disc 1GB micro sd card. i formated the card with my computer, the card works. i insert it into my phone and it's not being reconised, why is this? I've asked this on other android forums and no reply, could some people atleast help with one of the problems? i'm new to android phones..
