Can I find my iPhone by tracking its phone number? - 1

Alright, so my dad's on vacay and he's the only one who might know the iCloud info.
The sad part is that, he doesn't remember his info, so iCloud would be useless.
The most I can think of, besides all the complicated apps and whatever, is to track the phone number. I'm not sure how besides going to the police, but I'm not sure if my idea is possible.
I just really my iPhone 5 back and I know that it's stolen because someone watched Youtube videos and deleted them from my history. Security at my h.s. Said that on the same day someone else lost an iPhone, it was sold thrice. So I'm not sure of my chances of finding it, but it has my Gmail and my things, et cetera. I'm sure that it's not going to travel so far away from my city. Wherever it is, I'm determined to get it back.

Is there a free iPhone application to track my husband without him knowing?

Usually my husband would tell me he's close by whiles he's somewhere else, is there an app can actually track him and locate him without him knowing?

I have an app but it asks me to send my husband a message requesting his location, I really rather know without him knowing I know where he is. Will be waiting for answers.

Iphone 3gs stuck on searching after unlock?

I Have 16gb iphone 3gs, it has the new bootroom and also on firmware 4.3.2. The jailnbreak came out for it today and i jailbroke it using snowbreeze. I also unlocked it using ultrasnow and since ultra snow was broken on 4.3.2 i downloaded the ultrasnow fixer that also came out today that made it work on 4.3.2. When i put in my tmobile sim card, its stuck on searching, or somtimes i get no service but i never even get the t mobile bar. Also i did have 3g turned off. I tried with roaming on and off and still nothing

i tried switching airplane mode on and off plenty of times and still nothing. I don't know what to do.

If I change my password will I log out automatically?

My friend has the Facebook app and has logged herself and me on there before. (I said this was okay).
The app can automatically log me in on her iphone 5 without the "password" business.

If I changed my password, would it log me out of her Facebook app automatically and therefore she can't log in my account anymore?

Can I search email using gmail on an iPhone?

I'm stumped by this seemingly obvious feature.

One of the key things that makes gmail great is the ability to keep all your mail from forever and then search it using flexible google search when you need to find something.

I just got an iPhone and both the apple mail program, and even the google mobile app for iPhone appear to have left searching your mail off the list of capabilities. When you go to gmail.google.com from an iPhone, it recognizes that you are on an iPhone browser and redirects you to a fancy AJAX client that is very nice, but doesn't allow search.

There has to be a way? Anyone? I spent 2 hours searching the web for this issue and I have not found either a resolution, or even confirmation that you can't do it.

The google supplied gmail app on blackberry has search mail. Why would they leave that out on iPhone? It's a mystery.

If I can't search mail, I will probably return the iPhone. Browsing is nice, but there are a few must have email features…
