I've been having a random issue with wifi. It stay connected but, it stops sending data or gets slow. I can turn off wifi and then things are faster with 3G, like radar loading on weatherbug, app downloads, or this site. Then I'll turn wifi back on and it's fast for a few then slows down again. If I deal with it. It will speed back up and down at random. I guess it would be worse to have wifi work and not 3G, but it's annoying.
