PLEASE help me. 1) I am within the 30 day return window (I've had my iPhone 4 for about 2 weeks) 2) I get zero to 1 bars of 3G signal, about 60-75% of the time. The other times I randomly shoot up to full bars, but then it drops out after a few minutes. 3) I could restore it, but I don't think 3G strength has anything to do with restoring it. 4) I refuse to get a refurb from a Genius... I JUST got mine, I want a BRAND NEW iPhone 4 *** dammit (sorry for using the Lord's name in vain but this makes me angry that Apple could do this) What should I do?
