I can't receive text message on iPhone?

I just used a "Gevey sim" to "unlock" my iPhone 4s from AU KDDI(Japan) and the unlocking went pretty well. However, my iMessage is still using my former japanese number even when i'm nolonger in Japan. I have read forums for advice on how to change the number but all the advice give nthere has failed to work for me. With Wi-Fi, i can still use iMessage though with my old number, and without Wi-Fi, i can only RECEIVE text message from friends but when i send, all texts are "failed".
Why is it that i'm able to receive the sms messages and yet i can't send? And how can i change to my new number without using the old number?
Please advise.

Can DHS and Border Patrol really search notebooks and electronic devices?

Well, in 3 days I'll be leaving for a 14 day vacation to France from Massachusetts. I'm an American citizen but I have some concerns.Me and my girlfriend will be going together and are taking many belongings with us.

Me and my girlfriend are only 20 so maybe Customs agents will think because we're young they can take advantage of us?

I'm going to be taking my iPhone 5, laptop and notebooks with me. 2 of which, being the laptop and notebooks, have very personal and private information on there such as SSN, bank records and account information, sales and client information (for me and my dads business). As well medical records, etc…

I have heard through multiple sites as well as a friend who is a Customs agent, that the Department of Homeland Security and the Border patrol, whether I'm going in or out of the United States, can actively without a warrant or reasonable suspicion go through my laptop and download its records and files, search it thoroughly, as well as my phone AND even notebooks? Is this true or just an elaborate hoax?

I have no intent to cause damage to the US but these allegations seem to pretty intrusive on our privacy and personal property, wouldn't you say?

I'm going to a concert. Is HD photography allowed?

Every time I go to a concert at my local theater, they threaten to take away my camera so I end up hiding it and sneaking it in. I'm going to another venue in NYC and it says on their page

Q: What is appropriate etiquette for attending?
A: No flash photography or audio/video recording of any kind is allowed.

Does this mean I can simply turn my flash off and it will be OK to take photos with my Canon or do I have to use my iPhone? (I'm bringing both my camera and phone just incase)

Apple for car cassette for iphone?

So i have a question
I have a cassette player for my i phone in my car
It makes a lot of hissing sounds when you put in the cassette and when your playing a music
and the sound quality is bad
What I really want to do is, put it in my i phone that way when someone calls I can hear the person in my speakers
But with the cassette player I have now, it makes tic-kicking noises and the person who I'm talking to is hearing themselves echo.
So i'm thinking of buying an apple car cassette for iphone so its meant for apple i phones
Will that solve my problem? Ill buy the best one also? Amazon
