eligible for ANOTHER early upgrade ($399/$499 for 16/32GB) for the iPhone 4. However with the iPhone 4 I lowered my plan rates, so that I'm only paying $59.99 a month for everything ($39.99 for voice call, $15 data plan at 200MB, and $5 text plan). I'm worried that because my monthly bill is so low, compared to when I had the iPhone 3GS I was paying about $89.99 a month, that when iPhone 5 comes AT&T will not offer me the same early upgrade. Should I increase my plan to maybe $79 or $89 a month so that I have a better chance or am I ok? I could add more data or more minutes but I wonuld NOT use them. Trust me.
