Hey guys, I've only posted a few posts here and there but do a lot of reading on this forum. I currently own a 2nd gen iPod touch as well as an LG dumbphone. An iPhone 4 would be a huge upgrade for me obviously, however, Siri and the updated processor make the 4S look even better. Here is my issue. Never owning an iPhone I have a few concerns after reading many of the posts here. It seems like many have turned this forum into a complaint board for Apple recently. I do think Siri is something that I would get good use from but people are experiencing issues with down servers and others say it simply doesn't work. I know it's in beta so updates may come along to improve it. However, for the most part, are most people having good luck with Siri (I am in the US)? My next concern is battery life. I tend to make very few phone calls so the iPhone will be mostly for browsing and texts. At home, work, college, and many other friends/relatives homes I have access to wi-fi and only plan to use the 3G when in between. From what I understand, wi-fi browsing uses less battery than 3G. Are users finding this to be true? Is there a chance that the batteries in the 4S have some sort of fault and it's a gamble whether you get a good one or bad one? Third is screen quality. As stated, I have a 2G iPod touch and screen resolution has increased dramatically. I have played with a few iPhone 4's and only one iPhone 4S at Verizon. In general, are most users seeing at least the same quality in the 4S? What about yellowing? Does that seem to be an issue on the 4? Also, is there really a difference in the screen between the white and black model or are the differences simply in the perception of the user? Please respond to this if you have input. This is a chance for users who are having good luck with their 4S to point out the improvements. Are you happy you upgraded to the 4S or do you wish you stayed with the 4? Thanks!
