Question about Nokia 7373 Cellular Phone

7373 SMS Problem

My wife recently bought a 2nd hand 7373 locked onto T-Mobile. As she uses O2 this meant that she had to get it unlocked. This was done yesterday, and now the phone performs faultlessly- with one exception! This problem occurs in the Messages section- she can send messages as normal, and she can read incoming texts. The trouble is she can't re-refer to these texts later, as the Inbox can't be opened. When you hit the button you get the "Opening Page" banner, but then the screen just whites out for about 10 seconds (Although the battery and aerial symbols appear top left), following which you get dumped back to the opening page. I'm guessing corrupted software but could anyone offer a diagnosis, even a solution? Sure would save me a lot of earache!

I bought a 2nd hand nokia 7373 and when i put sim in it says sim regestration failed?

To unlock your nokia you will need to download and upgrade the firmware. To do this you need to buy a computer connection cable, an unlocking box box, the software to connect to pc and to find the unlocked firmware somewere on the web.The whole equipment is far more expensive then the phone itself, and this procedure always involve a small risk to damage the phone. Here it shows the howto.
Here are boxes for sale

There are codes to unlock phones distributed by big providers (eg Vodaphone, Orange, Tmobile etc.) by inserting code, but thisinformation is usually not provided to users. To get code you should call the provider who branded the phone, and probably they won't give you the code for commercial reasons.

If you have no practice with this, and you are not planning to do unlocking on more than one phone it could be convenient to pay the small fee required by phone shop, or use a mail unlock service like this :
