Hi All: I have an iPhone 1.0.2 that I use with TMobile. Everything work great but when I tried 1.1.1 Safari, Stocks, Weather did not work. They quit as soon as you try to go on line unless you use WIFI.
I had to downgrade back to 1.0.2: that cost me an entire day!
I'm wondering if I have been unlucky or 1.1.1 does not work 100% with T-Mobile and T Zones.
