Is it possible to disable all communications on a mobile phone (on any brand, like blackberry, iphone or android phone, or even an mp3 player like an ipod) this includes incoming/outgoing calls and text messages, and internet use - for a period of time like an hour or two?
In some way that can't easily be bypassed - like closing the app.
If you take out a SIM card out of a phone that uses them and there is no WiFi network around that should just about do it. Or you can use a phone that doesn't have WiFi (certain older Blackberries I think).
Alternatively something like the iPod Touch in a room without a WiFi network would also do it.
This may be cumbersome, but on a BB device you can likely inject keyboard events in order to turn off the radio. I don't know of a way to use straightforward APIs to disable the radio.
Not sure if this is your goal but you can programatically manipulate the inbox. If a new message arrives while you're "disabled" you can delete it from the inbox.

I just want to read sim card number and messages of mobile.
Can you please let me know how to resolve it.
Mobile devices don't provide that information for security/privacy reasons. You can access it in some low level Android API's but since this isn't portable we don't expose that.
Notice that apps like whatsapp, uber, gettaxi etc. all ask you to type in your phone number then a verification code sent via an SMS. That's exactly what JAT (which was built with Codename One) does.
I would like to use an arduino with a bluetooth module to modify the volume and skip songs on my phone.
All the information I found was about how to code an application that would communicate with a device via bluetooth, which isn't what I am looking for. I want to know what protocol I should follow to connect to an android device via bluetooth like a car radio would do.
My goal is to be able to use my device as a remote to control the built-in music application.
I think you are looking for the AVRCP protocol. Please send more info about your hardware so I can digg a better answer (if you need more, anyways...).
I have questions about programming in BlackBerry Devices OS 5 - 7. Is there a listener that can listen if the device is just connected to internet connection? The task of my app is that if the device is connected, it will send a http request right away.
Looking forward to it.

The listener you want is called CoverageStatusListener. Have a look at the API: CoverageStatusListener and CoverageStatusListener OS6.0+. Note the two flavours - you might want to use the extended version in your OS 6 and above apps.
But that said, coverage is only 1/2 the story. You might have good coverage but no access to the specific web site you are targeting. Another common problem is things like WiFi Hotspots - you can be talking quite happily on WiFi, but unless you have signed in to the Hotspot, you are not going to be able to communicate with your web site. So the many links that have already been provided by Signare (in the comments for your question), are useful. Here they are again, plus one more that I think is useful:

I want to develop an interface in my computer that will send sms from a text box to the computer attached phone(which has gsm based SIM) and phone will deliver that sms to a particular number(the number will also be given in text field).
I want to know what are the tools i may use for this purpose.What programming languages will be better for this kind of job?(java/.net/php/UNIX shell script).
Somewhat different in terms of use, but the following question probably can get you started with some of the research:

You could download a program called gnokii (I think it works both on Linux and Windows, please check the website). You can connect a very cheap Nokia mobile phone (check the list that are compatible) and send instructions to the cell phone using this program, like sending sms.
I did this some years ago with a very cheap Nokia phone. Of course I had to pay for each SMS sent, but this depends on the plan of your operator.. in my case I bought a SMS packpage for 6 bucks, then I could send 120 SMS (I'm from Brazil, check your location).
I would like to create application for Windows Phone 7, which will be communicating with desktop application via Bluetooth/Wi-Fi. Is there any API in Silverlight, which allows to use Bluetooth/Wi-Fi programatically?
Looks like bluetooth is going to be standard in the chassis spec. Unfortunately at this stage there is no api exposing Bluetooth functionality in the SDK. I think we'll have to wait and see on this one.
I understand devices will be able to inherently connect over wifi the same as 3g. No low level wifi specific api's known at this stage.
