Really, this is not an iPhone only blog but I have been consumed with my iPhone 3G like so many others. As you can guess I did update to the latest 2.1 firmware and now my iPhone has the old familiar stability that my 2G iPhone had.
I have seen a drastic increase in 3G availability and signal strength since the update. At my house I would usually have only one bar for 3G or full bars for Edge. Now I have four solid bars of 3G everywhere in my house.
The other significant differences that I have seen are that my contacts, SMS, and camera all load up a whole lot quicker (the camera could still be quicker though in my opinion).
My wife had been having trouble with her 3G in that it would not want to check here Gmail account. She would sometimes have to reboot it to get it to work. I updated her phone this morning and she has not had the problem since.
I think Apple may have gotten the 3G to the point of stability that my 2G phone was when I first got it (I got it about 2 1/2 months after they came out). When I got it the updates that Apple pushed out were feature updates as opposed to bug fixes.
I hope it is smooth sailing from here on out 🙂 .
