hi, i purchesed a Unlocked LG POP (GD510) but i read that it is not a 3G Phone, i have a 3G sim card and i was wondering if there will be any compatability issues with the sim card and phone. If anyone has purchased the Unlocked LG GD510 and has a 3G sim card can you please inform me of any problems or issues i might have to be aware of?

Thank you very much , XpliiCiT
