OP, where are you? Have you deserted this super sweet poll you created? Are you going to clarify which iPhone model this is regarding? If not, I'll make the assumption that it's regarding the iPhone 4S. Seems like a pretty safe assumption to me.
Okay, that being the case, I don't believe there is any antenna issue with the 4S. Do you believe otherwise? If so, I'm sure you will eloquently describe this issue to us all.
Battery drain is natural. However, there does appear to be an issue with poor battery life for some users of the 4S but Apple has indicated, at least publicly, that it is related to iOS 5 and not the 4S itself. Perhaps there is more to come from Apple on this one.
Screen display yellow. I've seen arguments throughout these forums where some think it's fine and others don't like the hue. Is it an "issue"? Perhaps others will chime in on this one.
"OverHeat". What? Please clarify.
Lastly, Wi-Fi/3G. I personally think Wi-Fi/3G is the biggest issue of them all. I mean, really? 2G is soooo much awesomer. Who in their right mind would want faster data on their handheld device? Just seems ridiculous, to me.
Anyway, I love this thread. A lot. I think it's going to go really far in terms of................eh, **** it, this is stupid.
