iPhone 4 loses Wi-Fi network

[RandyS]

My iPhone 4 loses my Wi-Fi network after logging in from screen saver mode. It never did this until a week ago. I have not updated the software. The phone version is 4.2.1. The modem version is 3.10.01. Every time in put my password in my phone I have to go to settings- WiFi – and chose my network….every other device works fine on my wireless network.
Thanks Randy

Go into settings and reset your network settings. That should the fix issue

In early February, Verizon will become the second wireless carrier in the United States to carry the iPhone. Up until now, AT&T had an exclusive in the US. Both will carry the iPhone 4, but there are some differences between the two. Here's what you need to know when selecting either the AT&T iPhone or the Verizon iPhone.
