What's wrong with my Iphone 4?

I'm wondering if my phone is having issues or if it is the network around here. I couldn't even make a call this morning, it wouldn't even start ringing, and i reset it twice, had full service the entire time. Now I'm in a different building, have one bar away from full service on 3G and my Iphone can't consistently stream pandora. , Really frustrated with either ATT or the iphone

Do a network reset, or is that what you did when you say "reset it twice"?

I am talking about the hold the power and home button reset, same thing? Or is this something else?

That is a hard-reset of the phone, (a bit like holding the power button down on a computer till it shuts down). Go into Settings > Network, then scroll down to the bottom where you should see something like "reset network" can't remember the exact wording of it.
Give it a go, could help with your problem.

Tried that, still being slow, It took about 15-20 seconds to open CNN mobile website which I don't regularly visit, but I think it's pretty quick, especially on full 3G service

It could be a problem with the network where you are, now that, that has been eliminated.
Try it again tomorrow and see if the problem persists or not.

Sounds good, thanks for your help!
