I have upgraded. The only issues I am having...
- Battery life is not good. Not sure whether this is an issue with the battery or the OS. But I am having to charge it a time or two a day...especially if I play any music.
- Slow processing. After playing with an iPhone 4 last weekend, the speed on this thing is depressing. For example, when I drag the bar to wake up the phone, sometimes it will lock up for as much as 5-10 secs before actually waking up.
- For some strange reason, I now have these new graphics that appear like clouds that part...especially when I unlock the phone. What the heck are those and how can I get rid of them? All they do is slow down the phone even more.
