Hi there, recently got myself an iPhone4. I have a question, how do you stop/block 3G completely? Thanks. That's all the question i have right now. Thank you. I do have reception issues if you guys want to know. Don't have the yellow tint on phone or camera indoors.. No light on the side leaks... Any other questions you guys want to ask me? I don't know the model number that you guys are looking for?
