Traveling with Airplane mode?

I'm going to the Philippines for vacation to visit family and friends in about 1 week. I live in Canada, but while you have airplane mode on, can you play the apps you currently have on your iPhone? My friend said you can't use airplane mode if your travelling very far, such as from Canada to Philippines, and can only use airplane mode if your travelling to a short distance such as Canada to Seattle. Just wondering if you can actually turn on airplane mode while flying internationally and if you can play game apps on your phone while you have airplane mode on.

Does an iPhone 4s work on with T-Mobile?

I'm not crazy about the rate plans the iPhone 4s gives you. They're expensive, but the iPhone 4s is a fantastic phone. I have many Apple products and I like what they offer. Therefore, I'm wondering if you buy an unlocked iPhone 4s, would it work with T-Mobile?

IPhone hotspot without data roaming?

I'm roaming and have data roaming turned off. I would like to use the Wi-Fi network my iPhone is connected to to provide Wi-Fi for a laptop. The laptop does not connect to the hotspot until data roaming is turned on, but this is what I'm trying to avoid. How can I get my laptop to connect to my iPhone and then by extension to the Wi-Fi network? The laptop can't connect to the Wi-Fi directly for other reasons.

My iPhone 4 just got stolen today, can they use it still?

I had it on Unlock with no password. I didn't realise my phone falling out of my pocket when getting out from my car so whoever found it, made a stupid facebook status update and clocked my phone. (He probably used his simcard next) Will he still have access to my personal things? I changed my facebook and email password. I didn't have the app Find my iphone on it so i won't know where it is.

I called the service provider and asked them to lock my phone and they said they will lock the sim and to lock the phone it will take 4hrs or so. So if the phone is locked, will they STILL be able to use it?

My iphone won't reboot and it shows a grey screen or BLUE screen? - 1
