I was really excited to get the iPhone 4S and finally abandon AT&T. Now, don't get me wrong, I absolutely love Apple and have been there on day one to get every iPhone. This is more of me expressing my hatred for... whatever is causing these issues. First of all, I'll say that I switched to a new account on Sprint the day the 4S came out; first time being on Sprint. I've been desperately hoping that all the issues I've been having are because of Sprint's network getting slammed by new iPhone users. First of all, Siri doesn't work 1/3 of the time, even with full bars and 3G. It just says it has trouble connecting to the network. Now, at home, I get 1mbps up/down, so I'm not sure what the issue is here. Secondly, at random times when going from place to place, literally like two feet, the "3G" switches to a "o" symbol when under heavy data load, or really just trying to load any data at all. Note: this happens even when I don't move at all and am trying to load data. It seems to happen more often when trying to use Siri. Third, similar to the "o" symbol, at random times I'll get switched to the "Extended" network? The Sprint will change to Extended. Not sure why. This all seems to happen in most places I go to daily. Both the Extended switch and the "o" switch seem to have an impact on data speed, though I can't say for sure. In some places, I won't get any service at all and I will have one bar with the "o" symbol. If I walk ten feet in another direction, I get full 3G restored. This doesn't happen as often as the other issues, but still has happened in the last few days. The weird thing is, I know a couple of friends on Sprint and they've never complained about their coverage... which is why I have hopes that it's not related to Sprint and I didn't just lock myself into a network with poor coverage for two years. What do I do? Is it the iPhone? Is it Sprint? Side issue, the phone heats up very frequently and battery discharge is just ridiculous compared to my iPhone 4. I had to purchase a Mophie battery pack to last through the day. I really don't understand why, the last time I experienced something like this was when I was running iOS 5 beta on my 4. Please, someone help, I'm trying so hard to love this phone, and I really do, these issues just get in the way.
