Dear all, I moved to my new iPhone 4 since the old one (after a replacement of a back cover with a cheap one) after a fall lost the chromed part of volume button and power button. Now that I do not need my old 3G, I'd like to replace these two parts not being in a hurry. But... I'd prefer to go for an "easier" approach. I'd like to buy another back cover that already includes buttons in order not to have to completely dismantle the phone. Could you recommend me any on line shop where to buy these parts? Thansk in advance.
